9. a bullet is moving at a speed of 367 m/s when it embeds into a lump of moist clay. the bullet
penetrates for a distance of 0.0621 m. determine the acceleration of the bullet while moving
into the clay. (assume a uniform acceleration.)

In a set amount of time, a battery supplies 25j of energy to an electric circuit that includes two different loads. one of the loads produces 10 j of heat energy during this time interval. how much heat energy is produced by the second load in this time? explain your answer

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
