Determination of Height for a Dropped Object

How long did it take for a helicopter to drop fertilizer onto a field?

A. 3.5 seconds

B. 6.13 meters

C. 120 meters

D. 17.15 meters

The fertilizer was dropped from a height of 60 meters.

To find the height at which the fertilizer was dropped by the helicopter, we can use the formula h = 1/2 * g * t^2, where h is the height, g is the acceleration due to gravity, and t is the time. Since the time is given as 3.5 seconds, we can substitute the value in the formula and solve for h. The acceleration due to gravity is approximately 9.8 m/s^2.

Using the formula, we have h = 1/2 * 9.8 m/s^2 * (3.5 s)^2 = 60 meters. Therefore, the height at which the fertilizer was dropped is 60 meters.

Next time you see a helicopter dropping fertilizer, remember that it took 3.5 seconds for it to reach the height of 60 meters!
