Question

15
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 0.105 m/s2. How
much time will it take for the body to stop?
PLEASE IT IS URGENT​

Answer 1

Answer:

Explanation:

u=0.5 m/s

a=-0.05 m/s²

v=0

By firs t 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

Answer 2

Answer:

u=0.5m/s a=-0.5m/s2 v=0

• t =(v-u)/a
• =(o-0.5)/-0.5s
• =o.5/0.5=1s
