Question

A ball of mass 250 g was moving with a velocity 10 m s-1 and after 6 s, its velocity becomes 28m s-1. Find force applied on the ball.

Answer 1

Answer:

The answer of the question is 0.75 Newton

Explanation:

F = ma

Force = Mass × Acceleration

Mass = 250 grams = 0.25kg

V = 28,U = 10 ,T = 6 Seconds

A = V-U/T

A = 28- 10/ 6

A = 3m/s²

F = 0.25 * 3

= 0.75 Newton
