Question

A bullet with a mass m = 7.89 g and an initial speed v0 = 334 m/s is fired into a ballistic pendulum.

A. What mass must the bob have if the bullet-bob combination is to rise to a maximum height of 0.115 m after the collision?

An air cart 1 of mass 3.06 kg and speed of 0.270 m/s moves toward a second cart 2 of mass 1.13 kg , that is at rest. When the carts collide they stick together and move as one.

a)What is the final speed of the carts?

B)How much kinetic energy is lost as a result of the collision?
