• Draw the diagram with coordinate axes for both.
• 1. A small steel ball is dropped from a roof of a building. It starts from rest and falls freely. Compute its position and velocity after 4.0 s.
• 2. A ball shoots horizontally from a point 0.8 m above the ground and strikes the ground on the horizontal distance 1.5 m from the shooting point.
• A) Find the time of flight of the ball.  
• B) Find the magnitude of the initial velocity of the ball.
• C) Find the magnitude and direction of the velocity of the ball just before it strikes the ground.
