4. A ball of mass 200 g had a speed of 2.0 m/s at position 1. Position I is 4.9 m from the ground. If the height at position 2 is 31.3% of the height at position 1 and the ball is about to hit the ground at position 3, write the kinetic energy (K), gravitational potential energy (U), and total mechanical energy (E) at positions 1, 2 and 3 indicated in the figure. (Assume the air resistance is negligible.) (Show work for full credit) UM K- E- K- K= U K- E- 4. A ball of mass 200 g had a speed of 2.0 m/s at position 1. Position I is 4.9 m from the ground.
