a scared kangaroo clears a fence that is 2.44 meters tall. what is the vertical component of the kangaroos velocity at take off (vfi) ? if the horizontal component of the kangaroos velocity is 4.80m/s at what angle did the kangaroo take off the ground? (hint: at its maximum height the kangaroos vertical velocity is 0)

Answer 1

Vfi^2 = 2gH
H = 2.44 m, g = 9.8 m

Solve for Vfi, the initial vertical component.

Vfi/4.80 = tanA

Solve for the angle A.

Answer 2

Vertical component is 6.915 m
