Answer:

h = 289 feet

Explanation:

Comment

You need two givens to use in the formula to solve for the third.

Formula

v = sqrt(2*g*h)

Givens

V = 136 ft/s

g = 32 ft/s^2

h = ?

Solution

v = sqrt(2*g*h) Put the givens into the formula.

136 = sqrt(2* 32 * h) Square both sides

136^2 = sqrt(2*32*h)^2 Expand

18496 = 64* h Divide by 64

18496/64 = 64*h/64

289 feet = h

So the object must fall 289 feet before it reaches 136 m/s
