Question

In a bizarre but harmless Superman fell from the top of the Eiffel How fast was Superman traveling when he hit the ground 7.80 seconds after falling ?

Answer 1

Vf = final velocity
Vi = initial velocity
g = acceleration due to gravity
t = time

Vf = Vi + gt

Vf = 0 + (9.8)(7.80)
Vf = 76.44 m/s
