Question

Daneil is bouncing on a trampoline. After a certain bounce he leaves the ground traveling at a speed of 2.54 m/s. How far into the air does he go?

I need helllpppp I'm so bad a physics, I need to know what formula to use..

Answer 1

recall your equation of motion. In this case, the height, as a function of t is

h(t) = 2.54t - 4.9t^2

This is just a parabola, with the vertex at

t = -b/2a = 2.54/9.8 = 0.26

So, just plug in t=0.26 to find the maximum height, h(0.26)
