Question

A Trolley while going down an inclined plane , has an acceleration of 2cm/s2
. What will
be its velocity 3 seconds after the start ?

Answer 1

Answer:

6 cm s -1

Explanation:

Initial velocity is: u=0

Time is: t=3s

Acceleration is: a=2 cm s

−2

From first equation of motion:

v=u+at

v=0+2×3=6 cm s

−1
