A body starts to slide over a horizontal surface with an initial velocity of a 0.5 ms-1. Due to friction, its velocity decreases at the rate of 0.05ms-2. How much time will it take for the body to stop?

here , 

u = 0.5 m/s 

a = - 0.05 m/s²

as v = 0 ( body finally comes at rest)

and we know 
 
a = v - u / t 

- 0.05   = 0 - 0.5 / t 

- 0.05 t = - 0.5 

t = -0.5 / 0.05 

t = 10 seconds
