Compute all parts of following problem:
Problem: Suppose you throw a 0.069-kg ball with a speed of 18.5 m/s and at an angle of 35.5° above the horizontal from a building 11.5 m high.
Part A: What will be its kinetic energy when it hits the ground?
Part B: What will be its speed when it hits the ground?
I need help to find its kinetic energy when it hits the ground.
