A child kicks a ball at a speed of 52 m / s at an angle above the horizontal. The ball is in the air for 3 seconds before hitting a vertical wall, which is located at a horizontal distance of 120 m from the canyon.
a) What is the value of the angle?
b) How high does the ball hit the wall?
c) What is the magnitude of the displacement of the ball?
d) What angle causes the ball to hit the wall? Is the angle above or below the horizontal?

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
