suppose you kick the ball 30 degree angle with horizontal axis with the veloctity 12m/s from the 50m high tower. describe the motion of the ball and draw the diagram with known quanities. how long will it take to reach maximum height? what is the maximum height ball reach? how long will it take to reach the ground? what will be the velocity when it reaches the ground? remember to write down x and y components and get the resultant.

MATLAB Grader CONTENTS For this problem you will model a field goal attempt in an NFL football game as a simple projectile motion problem. For a field goal attempt, the ball is snapped seven yards back from the line of scrimmage, where the place holder holds the ball on the ground for the kicker. For a successful attempt, the kicker must kick the ball through the uprights above the cross bar, which is ten feet high and parallel to the...
