Problem 3) A ball rolls off a tall platform with an initial horizontal velocity v0 = 25:71! S and hits the ground after 5 seconds. a) What is its impact velocity (speed and angle)? b) Find the height of the platform. 0) Find the horizontal distance traveled by the ball, measured from the "feet" of the platform. d) What is the velocity of the ball at t = 35 (speed and angle)? Problem 1) Backup your answers with a solution. Explain your reasoning with words or with mathematics. The diagram below shows the trajectories of three projectiles launched from ground level. Rank the trajectories according to a) Total flight time, Initial vertical velocity component, Initial horizontal velocity component, d Initial launch speed, greatest first. 2 3
