The work done by the machine is equal to the product between the force applied and the distance over which the force is applieds, so in this case:
And the power of the machine is equal to the ratio between the work done by the machine and the time taken:
The answer is C) rate of change of momentum. The answer is not initial or final momentum as the start and end points are not changing. On the other hand, the time it takes for the ball to change velocity is. This change relates to the change of momentum. Hope this helped :))
It would move to the right because the force is being applied from the left.
Answer:
So the mass of the second object M will be 1.951 kg
Explanation:
We have given mass of the first object 
and its velocity 
Mass of the second object 
it is at rest so its velocity 
From conservation of momentum we know that
Initial momentum = final momentum
So 
M = 1.951 kg
Answer:
B= 4,000 km
Explanation:
I just took the test on edge :)
