Question

A body starts to slide over a horizontal surface with an initial velocity of 0.5m/s. Due to

friction its velocity decreases at the rate of 0.105 m/s2. How much time will it take for the body

to stop?

Answer 1

hey there
u = 0.5
v= 0
a = -0.105
t = ?
v = u +at
0 = 0.5 +(-0.105) * t
0.105 t = 0.5
t = 5/10 *1000/105
t = 100/21
t = 4.76 seconds :)
