How far will a free falling object have fallen from a position of rest when it's instantaneous speed is 10m/s?
A fugitive tries to hop a freight train traveling at a constant speed Of 4.5 m/s. Just as a empty box car passes him, the fugitive starts from rest and accelerates at a= 3.6 m/s squared to his maximum speed of 8.0 m/s. How long does it take him to catch up to the empty box car? What is the distance traveled to reach the box car?
How do you find displacement when all you have is time with no velocity, and then in order to find velocity you have to have displacement but you don't have that either?
At a highway speeds, a particular automotive is capable of of an acceleration of about 1.6m/s^2. At this rate how long does it take to accelerate from 80km/h to 110km/h. I know the formula would be v=v0+at. I just don't understand the converting. I would love an explanation on how to do this. I been stuck for a while.
