A6.0-kg block slides from point a down a frictionless curve to point b. after the block passes point b, a friction force opposes the motion of the block so that it comes to a stop 2.5 m from b. calculate the coefficient of kinetic friction between the block and the surface after position b.

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.

The force will determine the acceleration.

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?
