Question

a 3.2 kg box of

running shoes slides on a horizontal

frictionless table and collides with a

2.0 kg box of ballet slippers initially

at rest on the edge of the table, at

height h = 0.40 m. The speed of the

3.2 kg box is 3.0 m/s just before the

collision. If the two boxes stick together

because of packing tape on their

sides, what is their kinetic energy just before

they strike the floor?
