A body starts to slide over a horizontal surface with an initial velocity of 0.5 metre per second due to friction its velocity decreases at a rate of 0.5 m per second square how much time will it take for the body to stop

According to an equation of kinematics for linear motion,

v= u+at, where, v is velocity at time t . We have to finnd t . u=0.5m/s, the initial velocity. a=-0.5 m/s^2 (retardation). When body stops moving ,v=0m/s. Substituting these values,

t=-(0.5/-0.5)=1s.

Answer:

10s

Explanation:

v=u+at

0=0.2-0.02×t

0.02×t = 0.2

t=0.2/0.02

t=10sec
