Question

What is the magnitude of the instantaneous velocity (speed) of a freely falling object 25 s after it is released from a position of rest? Consider the acceleration of gravity to be 10m/s^2. Answer in unit of m/s

Answer 1

The instantaneous velocity of the object is 250 m/s

Step-by-step explanation:

Given;

time of the object motion, t = 25 s

acceleration due to gravity, g = 10 m/s²

The instantaneous velocity of the object is given as;

v = u + gt

where;

u is the initial velocity of the object = 0 (since it was released from rest)

Substitute the givens;

v = 0 + (10 x 25)

v = 250 m/s

Therefore, the instantaneous velocity of the object is 250 m/s
