Question

. A trolley while going down an inclined plane, has an acceleration of
5m/s2
.What will be its velocity 2 s after the start?

Answer 1

Answer:

Here we have, Initial velocity, u = 0 m/s Acceleration (a) = 2 cm/s2 = 0.02 m/s2 Time (t) = 3 s Final velocity, v = ? We know that, v = u + at Therefore, v = 0 + 0.02 × 3 m/s ⇒ v = 0.06 m/s Therefore the final velocity of trolley will be 0.06 m/s after start.

Answer 2

Answer:

Change in velocity = 10m/s

Explaination:-

Given:-

acceleration = 5 m/s^2

time = 2 sec

a = change in velocity[(Final velocity - initial velocity)] / time

5 = change in velocity / 2 sec

change in velocity = 5 m/s^2 * 2 sec

change in velocity(v - u) = 10 m/s
