Calculate the tension on the rope.
A. 57.89 N
B. 32.73 N
C. 69.84 N
D. 12.55 N

Answers

Hi there!

[tex]\large\boxed{\text{B. 32.73N}}[/tex]

To calculate the tension, we must calculate the acceleration of the system.

Begin with a summation of forces:

∑F = -M₁gsinФ + T - T + M₂g

Simplify and solve for acceleration: (Tensions cancel out)

[tex]a = \frac{-M_1gsin\theta + T - T + M_2g}{M_1+M_2}[/tex]

Plug in values. Let g = 10 m/s²

[tex]a = \frac{-3(10)(sin30)+8(10)}{3+8} = 5.91 m/s^{2}[/tex]

Now, to find tension, let's sum up the forces acting on ONE block. For simplicity, we can look at the hanging block:

∑F = -T + W

ma = -T + W

Rearrange to solve for T:

T = W - ma

We know the acceleration, so plug in the values:

T = (8)(10) - (8)(5.91) = 32.73 N

This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.

What is Gravitational contraction?

Gravitational contraction is the process by which a celestial body, such as a star, generates energy through the release of gravitational potential energy as it contracts and becomes denser.

Here,
This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.

As the sun contracted and became denser, the temperature and pressure in its core increased, leading to the initiation of nuclear fusion reactions. These reactions transformed hydrogen into helium and released a tremendous amount of energy in the form of light and heat, which has sustained the sun for billions of years.

(b) What is the maximum height above the ground that the tennis ball reaches? (m)

(c) When the tennis ball is at a height of 2.4 m above the ground, what is its speed? (m/s)

Answers

a). 1.2 s

b). 3.81 m

c) v= 6.8 m/s

d) v= 27.05 m/s

What is speed?

Speed is define as the distance per unit time. It is also define as how fast an object is  moving.

According to the question:

Height = 1.5 m , speed = 7.0 m/s.

a)By using 1st equation of motion

[tex]V = V_{0} + g*t.\\V = 0 \\V_{0} = 7.0 m/s.g = -9.8 m/s^2\\0 = 7 + (-9.8 m/s^2)*t\\t = 1.2 s[/tex]

b.

[tex]h = 1.5 + V_{0} *t + 0.5g*t^2\\V_{0} = 7.8 m/s\\t = 1.2s , g = -9.8 m/s^2\\h = 3.81 m[/tex]

c.

[tex]V^2 = V_{0} ^2 + 2g*d\\V_{0} = 7.8 m/s\\g= -9.8 m/s^2.\\d= 2.2-1.5 = 0.7 m\\V = 6.8 m/s[/tex]

d.

[tex]V^2 = V_{0} ^2 + 2g*h\\V_{0} = 0\\g = +9.8 m/s^2.\\h = 6.8 m\\V = 27.05 m/s[/tex]
