Question

A body dropped from certain height reaches the ground after 4 seconds.

Average velocity of that body during its motion is​

Answer 1

Answer:

Here the answer is 39.2 m/s

Explanation:

We know that acceleration = V2 - V1 / t

Gravitational acceleration = 9.8m/s

Therefore

9.8 = V2 - 0 / 4

V2 = 9.8 × 4

= 39.2m/s
