Train car A is at rest when it is hit by train car B. The two cars, which have the same mass, stick together and move off after the collision. How does the final velocity of train cars A and B after the collision compare to the initial velocity of train car B before the collision?.
The value of the final velocity of train cars A and B after the collision compare to the initial velocity of train car B before the collision is [tex]v = \frac{ \ m_bv_b_1}{m_a \ + \ m_b}[/tex].
According to the principle of conservation of linear momentum, the total momentum before and after collision is conversed.
[tex]m_av_a_1 + m_bv_b_1 = v(m_a + m_b)[/tex]
where;
[tex]v_a_1 \ \ and \ \ v_b_1[/tex] are the initial velocity of the cars before collisionv is the final velocity of the cars after collisionsince the train car A is at rest, [tex]v_a _1 = 0[/tex]
[tex]m_bv_b_1 = v(m_a + m_b)[/tex]
The relationship between the final velocity and initial velocity of the cars is given as;
[tex]v = \frac{ \ m_bv_b_1}{m_a \ + \ m_b}[/tex]
Thus, the value of the final velocity of train cars A and B after the collision compare to the initial velocity of train car B before the collision is [tex]v = \frac{ \ m_bv_b_1}{m_a \ + \ m_b}[/tex].

Explanation: i just answered the problem
The 5.0-m-long rope in (Figure 1) hangs vertically from a tree right at the edge of a ravine. A woman wants to use the rope to swing to the other side of the ravine. She runs as fast as she can, grabs the rope, and swings out over the ravine.
When she's directly over the far edge of the ravine, how much higher is she than when she started?
Given your answer to Part A, how fast must she be running when she grabs the rope in order to swing all the way across the ravine?
She is 1.0 m higher than she is when she started. The speed at which the woman must be running when she grabs the rope is 4.427 m/s
Suppose we consider the Figure 1 to be a right-angle triangle;
where;
the hypotenuse is the rope = (5.0 m),the opposite side is the ravine = (3.0 cm) and;the adjacent is the slant imaginary distance = (x)∴
Using Pythagoras rule;
(hyp)² = opp² + adj²
5.0² = 3.0² + x²
x² = 25 - 9
x² = 16
x = √16
x = 4 m.
When she is directly over the far edge of the ravine, the height at which she is far higher than where she started is:
= 5cm - 4cm
= 1 cm
The speed at which the woman must be running when she grabs the rope can be determined by taking both the potential energy and kinetic energy of the system, which can be computed as:
mgh = 1/2 mv²Making the speed the subject of the formula, we have:
[tex]\mathbf{v = \sqrt{2gh}}[/tex]
[tex]\mathbf{v = \sqrt{2\times 9.8 \times 1.0}}[/tex]
v = 4.427 m/s

Hello guys! Can u please help me with physics. I translated it in English. Can yall help me please how much u can!!
A body 60 m above the ground shall be thrown vertically upwards at an initial speed of 20 m / s. Air resistance can be ignored!
1. How high will the body fly from the point of ejection?
2. What is the maximum height it will reach above the ground?
3. How long does it take for the body to reach its highest point from the moment of expulsion?
4. After how long after the expulsion will the body fall to the ground?
5. What is the speed of the body at the moment of falling to the ground?
1. Since the body is thrown vertically upward, the only force acting on it as it rises and falls is gravity, which causes a constant downward acceleration with magnitude g = 9.8 m/s². Because this acceleration is constant, we can use the formula
v² - u² = 2a ∆x
where
u = initial speed
v = final speed
a = acceleration
∆x = displacement
At its maximum height, some distance y above the point where the body is launched, the body has zero velocity, so
0² - (20 m/s)² = 2 (-9.8 m/s²) y
Solve for y :
y = (20 m/s)² / (2 (9.8 m/s²)) ≈ 20.4 m
2. Relative to the ground, the body's maximum height is 60 m + 20.4 m ≈ 80.4 m.
3. At any time t ≥ 0, the body's vertical velocity is given by
v = 20 m/s - gt
At the highest point, we have
0 = 20 m/s - (9.8 m/s²) t
and solving for t gives
t = (20 m/s) / (9.8 m/s²) ≈ 2.04 s
4. The body's height y above the ground at any time t ≥ 0 is given by
y = 60 m + (20 m/s) t - 1/2 gt²
Solve for t when y = 0 :
0 = 60 m + (20 m/s) t - 1/2 (9.8 m/s²) t²
Using the quadratic formula,
t = (-b + √(b² - 4ac)) / (2a)
(and omitting the negative root, which gives a negative solution) where a = -1/2 (9.8 m/s²), b = 20 m/s, and c = 60 m. You should end up with
t ≈ 6.09 s
5. At the time found in (4), the body's velocity is
v = 20 m/s - g (6.09 s) ≈ -39.7 m/s
Speed is the magnitude of velocity, so the speed in question is 39.7 m/s.

A girl pushes her little brother on his sled with a force of 300 N for 750 m.
How much work is this? _______________
How much energy is used?__________
How much power does she use if it takes her 25s?_________
How much power does she use if she runs and complete the 750m in 10s?________
Answer:
W = F× d
= 300×750

E = 225000
P = 300×750/25 = 9000
P = 300× 750/10 = 22500
If the depth of water in a well is 10m, what is the pressure exerted by it the bottom of the well ? ( Use g = 10 m/s2)
show the process as well
Answer:
The precise answer depends on the density and therefore the temperature of the water, but we can obtain a reasonable approximation by assuming that the density of the water is 1000 kilograms per cubic meter (kg/m³).
Since the depth of the water in the well is 10 m, the volume of water directly above an area A of a square meters (m²) at the bottom of the well is 10×a m³.
Since the density of the water is 1,000 kg/m³, the mass of water directly above area A is (1,000 kg/m³) × (10×a m³) = (1000×10×a kg) = 10,000×a kg.
Since g = 9.8 m/s², the force of gravity acting on the water directly above area A is (9.8 m/s²) × (10,000×a kg) = 9.8×10,000×a N (newtons) = 98,000×a N.
So the pressure of water acting on area A is (98,000×a N)/(a m²) = (98,000×a)/a N/m² = 98,000 pascals (pa). And since A could be any given area at the bottom of the well, this is the pressure at any point at the bottom of the well.
So the pressure at the bottom of the well is 98,000 pascals (or 98,000/101,325 standard atmospheres = 560/579 atmospheres ~ 0.967 standard atmospheres).

Explanation:
You throw a can of cranberry sauce straight up in the air with an initial velocity of 12 m/s. What is the maximum height the baseball reaches above your head.
Answer:
Δx=7.35m
Explanation:
This is a free fall problem (g= -9.8 m/s²).
Displacement: ? <--- what you're trying to find (max height)
Initial Velocity: 12 m/s
Final Velocity: 0 m/s <-- since the can will land back in your hands
Time: Missing <-- not needed to solve
Acceleration: -9.8 m/s²
The equation that you will use is vf²=vi²+2aΔx
Now plug the information into the equation!
(0m/s)²=(12m/s)²+2(-9.8m/s²)Δx
Multiply the 2 with the acceleration (-9.8m/s²)
(0m/s)²=(12m/s)²-19.6m/s²Δx
Now you need to square the final and initial velocity
0m/s=144m/s-19.6m/s²Δx
Move 144 to the other side of the equal sign
-144m/s=-19.6m/s²Δx
Divide both sides by -19.6m/s²
7.346m=Δx
You can round it to the tenth or hundreth place, up to you!
For this example, I'll round to the hundredth...
Δx=7.35m
I would double check this answer or review it yourself to see if it's correct.

1. When a 50,000 kg rocket blasts off there is a large force that acts on the rocket at the moment
of take off. In 0.137 seconds, the rocket suddenly has traveled 4.2 meters. What force from
the rocket engines caused the acceleration? (Hint: first find acceleration.)
Hi there!
We can begin by calculating the acceleration using the kinematic equation:
d = vit + 1/2at²
Since the rocket starts from rest, we can rewrite this as:
d = 1/2at²
Plug in given values:
4.2 = 1/2a(0.137²) ⇒ a = 447.55 m/s²
Now, we can use Newton's Second Law to find the appropriate force:
∑F = m · a
∑F = 50,000 · 447.55 = 22,377,500 N
