A 1-kg pellet travels with velocity 160
m/s to the right when it collides with a 39-kg
hanging mass which is initially at rest. After the
collision, the pellet remains lodged in the hanging mass, i.e., it
is a completely inelastic collision. The hanging mass (+pellet)
then swings upward and reaches a maximum height hmax
before swinging downward again. Assume that no external forces are
present and therefore the momentum of the system is
conserved.
What is the velocity vf of the hanging
mass + pellet immediately after the collision?
m/s

What is the final kinetic energy
Kf of the hanging mass + pellet
immediately after the collision?
J

What is the maximum height hmax of the
swinging hanging mass + pellet in
centimeters?
