Question

a body starts rolling over a horizontal surface with an initial velocity of 0.5 m/s due to friction its velocity decreases at the rate of 0.05 m/s square how much time will it take for the body to stop

Answer 1

u=0.5m/s a=-0.05m/s². v= 0 m/s t= ?
v=u+at
0=0.5+(-0.05)t
-0.5=-0.05t
t= 0.5/0.05
t= 50/5
t= 10 seconds

Answer 2

Solution:-
Its given that,
Initial velocity=0.5
Final velocity=0
Acceleration=0.05
Time=?
By using equation:-
v=u+at
$0 = 0.5 + ( - 0.05)t \\ 0.05t = 0.5 \\ t = \frac{0.5}{0.05} \\ t = 10$
Hence,time taken by body is 10second.
