a freely falling object starts from rest. how long will until it hits the ground if it is dropped 36m above the ground?

Given:

Initial velocity (u) of the object = 0 m/s (Body starts from rest)

Height above the ground (h) = 36 m

Accelration due to gravity (g) = 10 m/s²

To Find:

Time taken (t) by the object to hit the ground

Explanation:

From equation of motion for object under gravity we have:

Substituting values of h, u & g in the equation we get:

less than one you can't create energy

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
