Animations - Make the Ball Bounce
Problem Statement:
Modify the pre-placed blocks to produce the following animation:
  • Have the ball bounce 8 times.
  • Use a different color for the ball when it bounces up and for when it bounces down.
  • Change the size of the ball - make it smaller.
  • Change the starting position of the ball so it begins bouncing from the ground and reaches a height of 18.
  • Change the speed of the bounce.
