A0.026 kg bullet is fired straight up at a falling wooden block that has a mass of 5.0 kg. the bullet has a speed of 750 m/s when it strikes the block. the block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occured. as a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a momentary halt at the top of the building. find the time t.
Answers: 3
= initial velocity of block as it is dropped = 0 m/s
= acceleration = - g
= time of travel
= final velocity of block before collision 
= mass of the bullet = 0.026 kg
= velocity of block just before collision = 750 m/s
= mass of the block = 5 kg
= final velocity of bullet block after collision = gt

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
