Question

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

Answer 1

Initial velocity (u) = 0 cm/s (Since, trolley is initially at rest)

Acceleration (a) = 2cm/s²

Time (t) = 3s

Final velocity (v) = ??

We know that :-

v = u+at

v = 0+2×3

v = 6 cm/s

v = 6/100 m/s

v = 0.06 m/s

Final velocity = 0.06 m/s

The final velocity of a trolley starting from rest having acceleration 2 cm/s² in time 3 seconds will be 6 cm/s or 0.06 m/s (in SI Unit).
