Question

a ball is falling freely from certain height. it reaches ground after 3second, if we 30m/s is the velocity of the ball while touching the ground, calculate the acceleration​

Answer 1

Explanation:

Initial Velocity = 0 m/s

Final Velocity = 30 m/s

acceleration = v - u

t

= 30 - 0

3

= 30

3

= 10 m/s^2

Answer 2

Answer:

Initial velocity = 0 m/s

Final velocity = 30m/s

acceleration = v - u / t

= 30 - 0 / 3

= 30/ 3

= 10 m/s -2
