Question

iv) A body starts to slide over a horizontal surface with an initial velocity of 0.2 m/s. Due to friction, it’s velocity decreases at the rate of 0.02 m/s^2. How much time will take for the body to stop? (a) 10 s. (b) 15 s. (c) 5 s. (d) 1 s III​

Answer 1

Answer:

correct option is (A)

10s.

v=u+at

0=0.2-0.02*t

0.02*t=0.2

t=0.2/0.02=10 sec.
