A person kicks a soccer ball with an initial velocity directed 53o above the horizontal. The ball lands on a roof 7.2 m high. The wall of the building is 25 m away and it takes the 2.1 s to pass directly over the wall. By what vertical distance does the ball clear the wall of the building? Ranvir and Kayla stand at the edge of a 50 m high cliff on the moon. Ranvir extends his arm over the cliff edge and throws a ball straight up with an initial speed of 20 m/s. Kayla throws an identical ball with the same initial speed, but she throws the ball at a 30 degree angle above the horizontal. For the following questions, justify your response with a calculation. Which ball reaches the peak of its flight more quickly after being thrown? Which ball has the greater vertical velocity when it hits the ground
