A bullet is fired into a large stationary absorber and comes to rest. Temperature measurement of the absorber show that the bullet lost 1960 J of kinetic energy and high speed photos of the bullet show that ir was moving at 965 m/s just as it struck the absorber. What is the mass of the bullet?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

The amount of potential energy possessed by an elevated object is equal to what?
