A cargo with a mass of 50 kg can withstand a maximum velocity of 26 m/s. If dropped on the moon, where the acceleration due to gravity is -1.6 m/s2, how long will it be in free fall?
Record your answer as a positive number (because time cannot be negative) and round to the whole number.
You do not need to include units.
Wouldnt the answer be 1.6 m/s²?
I am sorry if its not.
A runner decreases his velocity from 20 m/s to 10 m/s in 2.0 s.
What was his average acceleration?
We have that the average acceleration is
[tex]a=5m/s^2[/tex]
From the Question we are told that
Decreases his velocity from 20 m/s to 10 m/s in 2.0 s.\
Generally the equation for the average acceleration is mathematically given as

A race car accelerates from 0 m/s to 20.0 m/s with a displacement of 35.0 m. What is the vehicle's acceleration?
a 5.7 m/s2
b .84 m/s2
c 6.1 m/s2
d .29 m/s2
Explanation:
Using Equations of Motion :
[tex] {v}^{2} = {u}^{2} + 2as[/tex]
[tex]a = \frac{{v}^{2} - {u}^{2}}{2s} = \frac{400 - 0}{70} = 5.71msec^{ - 2} [/tex]

Explanation:
1 km/hr × (1000 m/km) × (1 hr / 3600 s) × 45 s = 12.5 m
Two grocery carts have the same initial total momentum. The two carts collide, and now cart B has a greater final velocity.
Which best describes the final total momentum of both the carts compared to the initial total momentum?
It is less if cart B has a smaller mass.
It is greater if cart B has a greater mass.
It is the same if no external forces are added.
It depends on the masses of cart A and cart B.
Answer: The anser is C
Explanation:
It is the same if no external forces are added.
Based on the principle of conservation of linear momentum, the final total momentum of both carts compared to the initial total momentum is the same if no external forces are added.
The given information;
two carts have equal initial momentum beforeafter collision, cart B has greater final velocityAccording to the principle of conservation of linear momentum, the total momentum before collision is equal to the total momentum after collision.
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
where;
m₁ and m₂ are the masses of the two cartsu₁ and u₂ are the initial velocities of the two cartsv₁ and v₂ are the final velocities of the two carts after collisionThus, based on this principle (conservation of linear momentum), the final total momentum of both carts compared to the initial total momentum is the same if no external forces are added.

Why us an element considered a pure substance
Explanation:
Hey there!!
An elements is called a pure substance because it is composed of only one kina of atoms in a fix proportion.
Hope it helps...
Answer:
Elements are pure substances because elements are always made up of same kind of particles.
Example:- pure Iron rod (iron is an element)is made up of many similar Iron atoms.
A ball is thrown upward. The total time the ball remains in the air is 14 s. a) With what speed was the ball thrown upward? b) What is the maximum height reached by the ball?
Answer:
a) Vi = 137.2 m/s
b) h = 960.4 m
Explanation:
a)
In order to find the initial speed we will use first equation of motion:
Vf = Vi + gt
where,
Vf = Final velocity = 0 m/s (since ball stops at highest point)
Vi = Initial Velocity = ?
g = - 9.8 m/s² (negative sign for upward moyion)
t = time interval = 14 s
Therefore,
0 m/s = Vi + (-9.8 m/s²)(14 s)
Vi = 137.2 m/s
b)
Now, we use second equation of motion to find height (h):
h = Vi t + (1/2)gt²
h = (137.2 m/s)(14 s) + (1/2)(-9.8 m/s²)(14 s)²
h = 1920.8 m - 960.4 m
h = 960.4 m

A biker starting from rest reaches a final speed of 3.0 m/s in 3 seconds. What is the acceleration of the biker?
Answer:
1 m/s²
Explanation:
Given:
v₀ = 0 m/s
v = 3.0 m/s
t = 3 s
Find: a
a = (v − v₀) / t
a = (3.0 m/s − 0 m/s) / 3 s
a = 1 m/s²
The Concord jetliner achieves a lift-off speed of 112 m/s in 20.0 seconds, starting from rest and traveling due east. What is the magnitude and direction of the average acceleration?
Answer:
5.6 m/s
Explanation:
The acceleration of any possible is the ratio of the velocity of the particle with respect to the time the particle takes in moving. It is mathematically represented as
a = v/t, with m/s² as it's unit, where
v = velocity in m/s
t = time taken in seconds
a = acceleration in m/s²
From the explanation above, we were given in the question that, the speed is 112 m/s and the time if took is 20 seconds, thus, the acceleration is
a = 112/20
a = 5.6 m/s²
Therefore, the magnitude of the acceleration is 5.6 m/s²

Elements located in the vertical column of the periodic table are of the same _______ and have _______ chemical properties.
A. group
B. period
C. similar
D. different
E. style
F. unlike
Answer:
I think its A & C
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Elements located in the vertical column of the periodic table are of the same group and have similar chemical properties, therefore the correct answer is option A and option C.
What is the atomic number?The total number of protons present in an atom is known as the atomic number of that atom.
While the atomic mass of an atom is the sum of the total number of protons and the number of neutrons present inside any atom.
The element belonging to the same group have approximately similar chemical behavior while on the other hand element belonging to the same period would have the same outermost shell.
The correct response is option A and option C because elements included in the vertical column of the periodic table belong to the same group and have comparable chemical characteristics.

Explanation:Flexibility and stretching: preventing sports injuries
Many may know about all the different types of sports around the world. Lots can leave serious injuries. All across the world more than 1.2 million people have been injured because of sports or maybe more than that. Most of the injuries have been kids. To prevent these injuries from happening. One thing is stretching if you don’t stretch your bones more than likely you are not into your flexibility and reflexus that for they are very weak. If there is not enough flexibility within your movement you are more than likely not able to stretch. It can help the growth within your bone as well. If you have growth in your bones then you will get less injuries. If you break a bone such as your leg or sprain there is a chance that you will have problems with that specific leg later on in life. To prevent these types of events from happening I say stretch before a sporting game. Stretching can help with the impact of your flexibility. For example, Olympic gymnasts are able to do lots of tricks because their bones have flexibility in their bones. That's not saying that they will not hurt themselves, it's just such a low risk because their bone grew strength and flexibility. Some people's bones can be very sensitive then others so it might be kind of hard for them to be flexible. Another way to help people with their bone flexibility is drinking milk. Milk helps grow your bones. This can help prevent sport injuries in many ways. Lots of people get hurt in football to be more specific because it's such a durable sport as in tough. If they drink a lot of protein and milk before a game maybe even Carbohydrates their bones will be ready for the game. Flexibility and stretching can go lots of ways when it has to do with your body.
