Rising and Falling Motion Solve each problem using the equations of acceleration motion. In each case, assume there is no air resistance. 1. A ball is thrown upward with an initial velocity of 2.8 m/s. How high will the ball rise? VI= 2.8 MS .VF = 0 , a= 9 - 9.8mis2 (2. 8)1 2x9. 0 19.8 2. A ball is thrown upward and reaches a point 0.64 m above its initial position at the top of its path. What was the ball's initial velocity
