Jim Guinn’s PHYS1111 Assignment # 3 1. A ball is thrown vertically (you don t know up or down) out of a window in a tall building. It takes 3.30sec to pass a point 20 meters below where it started. a.) What was the ball s initial velocity? b.) What is the velocity of the ball when it passes the point 20 meters below? 2. An object has a position as a function of time x(t) = 4m t 3 /s 3 + 5m t/s . a.) What is the object
