Jason kicks a ball off of a 15-m-high cliff. The kick is at an angle of 30 degrees above the horizon with a speed of 20 m/s. In this problem you will be ultimately solving for the distance from the cliff that the ball lands. 1. Solve for the time it will take the ball to hit the ground. 2. Solve for the horizontal distance from the cliff that the ball will land. r = r0 + V0t + 1/2at^2
