Question

A body starts to slide over a horizontal surface with velocity 0.5m/s. Due to friction , its velocity decrease at a rate of 0.5m/(s*s) . How much time will it take for the body to stop​

Answer 1

here,v=0.5m/s

u=0 , a=0.5m*m

we know that

v=u+at

0.5=0+0.5m*m*t

0.5=0.5m*m*t

0.5/0.5=t

1s=t
