A 1.5kg apple falls from a tree. If the apple falls for 2.75s before striking the ground, determine how far in meters the apple dropped before hitting the ground

s = 37.81 m

Explanation:

Given that,

Mass of an apple, m = 1.5 kg

The apple falls for 2.75s before striking the ground.

We need to find how far the apple dropped before hitting the ground. It means we need to find the distance covered. Using the second equation of motion to find it :

u is initial velocity, u = 0 (at rest)

So, Apple dropped 37.81 m before hitting the ground.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
