Question
A block of mass 20 kg moves along a frictionless surface, and is in a collision course with a
sphere of mass 10 kg tied to an inextensible rope of length 6.00m. If the block collides with the
sphere with a velocity of 5.00 m/s, as shown in the figure, and the coefficient of restitution is e =
0.800, determine the following. Neglect friction and air resistance.

3. To solve for the maximum height, H, which of the following concepts cannot be used?
The kinetic energy of the sphere just after its collision with the block is equal to its potential energy at the maximum height, H.
The kinetic energy of the sphere just after its collision with the block is equal to its kinetic energy at the maximum height, H.
The velocity of the sphere at the maximum height is zero.
The work done by gravity on the sphere will DECREASE the sphere's kinetic energy.
