Answer 1

Answer:

an

aceleration of 2 m/s. What will be its velocity 3 sec after

Answer 2

Explanation:

.

Initial velocity of a trolley, u=0 (at rest)Acceleration, a=2cms −2 =0.02m/s 2 Time t=3SAs per 1st law of motion,v=u+atHere V means velocity of a trolley after 3sV=0+0.02∗3=0.06m/s.∴=0.06m/s..
