4. An airplane must achieve a velocity of 71 m/s for takeoff. If the runway is 1000 m long,

what must the acceleration be?

A ball starts from rest and accelerates at 0.500 m/s2 while moving down an inclined plane 9.00 m long. when it reaches the bottom, the ball rolls up another plane, where it comes to rest after moving 15.0m on that plane.

You accelerate your 1500 Kg from 2 m/s to 12 m/s in 2 seconds. How do you determine the cars acceleration initial momentum final momentum change in momentum the force required to do this?
