find the velocity of an object that has fallen 84 feet, round to the nearest hundredth

Answer 1

The velocity of an object falling can be calculated using the formula:

v = sqrt(2gh)

Where:
v = velocity
g = acceleration due to gravity (32 feet per second squared)
h = height fallen (84 feet)

Plugging in the values:
v = sqrt(2 * 32 * 84)
v = sqrt(5376)
v = 73.36 feet per second

Therefore, the velocity of the object that has fallen 84 feet is approximately 73.36 feet per second rounded to the nearest hundredth.
