Question

a body start to slide on horizontal surface with an initial velocity of 0.5 m/s.due to friction it's velocity decrease at the rate of 0.05m/s ?

Answer 1

we know that
 v = u +at
 
here
u = 0.5
 a = -0.05 m/s
v = 0 m/s

so, time taken to stop will be
t = -u/a
 = -0.5/-0.05
 
thus, t = 10s

Answer 2

Answer:10 second

Explanation:By using v=u+at
