Question

Q1.
A body starts to slide
over a horizontal surface
with an initial velocity of
0.5 m/s. Due to friction,
its velocity decreases at
the rate of 0.05 m/s2
(acceleration,
-0.05 m/s²). How
much time will it take for
the body to stop ?

Answer 1

Answer:

u=0.5m/s

v=0

a= -0.05m/so

v=u+at

0=0.5-0.05×t

t=0.5/0.05

t=10
