A person walking with a speed of 1.44 m/sec releases a ball from a height of h = 1.28 m above the ground. Use the point on the ground, directly below where the ball is initially released at the origin of your coordinate system.

(a) What is the ball's position at 0.25 seconds after it is released?

(b) What is the ball's position at 0.5 seconds after it is released?

(c) What is the ball's total velocity, speed and direction of motion at 0.5 seconds after it is released?
