43. Review. A boy starts at restand slides down a frictionless slide as in Figure P8.43. The bottomof the track is a height h above the ground. The boy then leavesthe track horizontally, striking the ground at a distance d asshown. Using energy methods, determine the initial height H of theboy above the ground in terms of h and d.
Here is what I have...Am I correct if not please providedetail
h=(1/2)g*t^2
t=â((2h/g) )
v*t=vâ((2h/g))
d=vâ((2h/g))
mgy=(1/2)mv^2
v^2=2gy
v=â2 gy
y=v^2/2g
