a) What is the speed of the ball at the top of its trajectory in m per second
b) What is the maximum height H reached by the ball in m?
c) What is the y-component of the initial velocity that the football is kicked at? 5.3 m per second?
d) What is the speed at which the football lands on the ground in m per second?
