Question

A body start to slide over a horizontal surface with an initial velocity of 0.5m/s.Due to friction,its velocity decreases at the rate 0.05m/s².How much time will it take for the body to stop.??
plz help me.. I will mark u as Brainlist ​

Answer 1

Answer:

If the system is under the application of friction force and no other force is applying on it then by using equation of linear motion

v = u + at

Here, v = 0.5 m/s , u =0 m/s and a = 0.5 m/s^2( acceleration is positive because it is in the direction of external force), then we have

0.5 =0 + 0.5t

=> t = 1 second
