You jump straight upward off a trampoline with an initial velocity of 30 km/h. How high above the trampoline will you reach?
v2=v1 + a x t & v2(square root)=v1(square root) + 2ad
The Attempt at a Solution
I tried 30km/h into the second equation (knowing that acceleration in 9.81) and that the vertical at its peak is 0 but my number is no were near the answer key
do i have to convert km/h to m? and where did i go wrong
