find the velocity of an object that has fallen 84 feet round to the nearest 100th

1 answer

The velocity of an object that has fallen a certain distance can be calculated using the formula:

v = sqrt(2gh)

Where:
v = velocity
g = acceleration due to gravity (32.2 ft/s^2)
h = height fallen (84 feet)

Plugging in the values, we get:

v = sqrt(2 * 32.2 * 84)
v = sqrt(5427.2)
v ≈ 73.68 ft/s

Therefore, the velocity of the object that has fallen 84 feet is approximately 73.68 ft/s.
