Description 
58

A putted golf ball rolls toward the hole. Simulation includes
break and velocitydependent friction.
The velocity vector for the ball is shown. 
59 
Golf balllinear motion with friction

includes velocitydependent friction.

Basketball bounces 
A basketball with an initial velocity in the xdirection bounces
on the floor. The ball loses energy with each collision and eventually stops.
Simulation uses setTrajectory instead of setForce in order to show the ball at the
instant that it hits the floor. Energy is lost with each collision but no particular
physical model is used to determine how much energy is lost due to a collision.
The velocity vector for the ball is shown. 
61 
Rocket with constant acceleration

The velocity vector for the rocket is shown.
