Micheal jordan's vertical leap is reported to be 48 inches high. find his takeoff speed.?

Question

plese tell me how you came upon your answer.

Thanks

Answer 1

Vo=Vf-1/2gt^2

Vo=-1/2gt^2

Answer 2

Use the law of conservation of energy..

Ek = Ep where Ek = Kinetic Energy and Ep = Potential Energy

(1/2)mv^2 = mgh

=>(1/2)v^2 = gh

=> v = sqrt(2gh)

Solve...

Yes thats y youuse the law ofconservation of energy...

substitute for g(gravity) and h(height) and you will get that takeoff speed...
