Question

A soccer ball is kicked from the ground and lands 2.2 seconds later. What is the initial vertical component of the ball's velocity and how high does the ball get above the ground?

Answer 1

time up equals time down

Vv = g t = 9.8 * 1.1

h = 1/2 g t^2 = 4.9 * 1.1^2

Answer 2

Y = Yo + g*t = 0 at max ht.
Yo + (-9.8)*1.1 = 0,
Yo = Initial ver. component.
