An object mass m1 falls from a height of h1.

Question

a. Write a formula for the velocity of the object just before it stikes the ground in terms of g,m1,and h1.

b. Write a formula for the velocity of the object at the half way point in terms of g,m1, and h1.

Answer 1

a. V^2 = Vo^2 + 2g*h1. Vo = 0.

b. V^2 = Vo^2 + 2g*0.5h1. Vo = 0.
