Question

A trolley, while going down an inclined plane, has an acceleration of 2 cm s-2.
What will be its velocity 3 s after the start?

Answer 1

Given:

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

Answer 2

Answer:

Correct option is A)

Given:

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
