Question

A body starts to slide over a horizontal surface with an initial velocity of 0.5m/s. Due to friction it’s velocity decreases at the rate of 0.05m/s square. How much time will it take for the body to stop

Answer 1

0.5×0.05m/s
good question

Answer 2

U=0.5 m/s

a=-0.05 m/s²

v=0

By first equation of motion, we have:

v=u+at

0=0.5-0.05t

0-0.5=-0.05t

-0.5=-0.05t

0.5/0.05=t

50/5=t

10 s=t

your answer is "t = 10s"

hope it will help you..
