Question

If a golf ball is dropped from the thirteenth floor of a building, ignoring air resistance, after falling for 7.00 seconds the speed of the ball will be?

Answer 1

Explanation:

We know that

V = U + at

Here, u is 0 and a is 9.8 which is acceleration due to gravity.

Thus,

V = 9.8 *7

V = 68.6 m/s
