Question

A BODY STARTS SLIDING OVER OVER A HORIZONTAL SURFACE WITH ANN INITIAL VELOCITY OF 0.5M/S. DUE TO FRICTION , ITS VELOCITY DECREASES AT THE RATE OF 0.05M/S . HOW MUCH TIME WILL IT TAKE TO STOP

Answer 1

Initial velocity (u) = (5/10) m/s
acceleration (a) = -(5/100) m/s^2
final velocity (v) = 0 m/s

using v =u +at
0 =(5/10) - (5/100)t
- (5/10) = -(5/100)t
(5/10)(100/5)=t
t =10 sec

Answer 2

according to me this is the answer
plz correct me if wrong
comment if correct
