Question

Acceleration due to gravity is 9.8 m/s^2. What will be the velocity of a freely falling body in 2 seconds after the fall?

Answer 1

The initial velocity of the freely falling body is = 0 m/s

The velocity is changing at rate of 9.8m/s

the velocity after 2 sec is 2 X9.8 = 19.6 m/s

Answer 2

The initial velocity of the freely falling body is = 0 m/s

The velocity is changing at rate of 9.8m/s

the velocity after 2 sec is 2 X9.8 = 19.6 m/s
