Question

The average velocity of a freely falling body is numerically equal to half of the acceleration due to gravity. The velocity of the body as it reaches the ground is numerically equal to:
  1. g
  2. g2
  3. g2
  4. 2g

A
g2
B
g2
C
2g
D
g
Solution
Verified by Toppr

We have average velocity =g2
Since it is a free fall, average velocity, v=St=12gt2t=g2, where t is the time of descent and initial velocity is zero.
