A package of mass is released from rest at a warehouse loading dock and slides down a 3.0-m-high frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 2 , from the bottom of the chute.
Suppose the packages stick together. What is their common speed after the collision?
Suppose the collision between the packages is elastic. To what height does the package of mass rebound?
A block sliding along a horizontal frictionless surface with speed collides with a spring and compresses it by 2.0 cm. What will be the compression if the same block collides with the spring at a speed of
The figure is the potential-energy diagram for a 500 g particle that is released from rest at A.
What are the particle's speeds at B, C, and D?
