A force of 0.04N acts upon a body.As a result the speed of the body changes from 0.30m/s to 0.10m/s in passing through a certain distance.Find the distance if the mass of the body is 1 kg.

 Initial Velocity = u = 0.3 ms^-1

 Final Velocity = v = 0.1 ms^-1

 Acceleration = Force / Mass = 0.04 / 1 = 0.04 ms^-2

 Distance = s = ?

 By v² = u² + 2as

(0.01)2 =  (0.03)2 + 2 x 0.04s

 0.0001 = 0.0009 + 0.08s

 0.0001 / 0.08 = 0.0009 + s

 0.00125 - 0.0009 = s

 s = 0.00035

 The distance travelled by the body is 0.00035 m

Thumbs Up!
