Question

A trolley while going down as included plane has an acceleration of 2m/s2 ,what will be its velocity 3 secs after the start?

Answer 1

Answer:

Initial velocity of a trolley, u=0 (at rest)

Acceleration, a=2cms −² =0.02m/s ²

Time t=3S

As per 1st law of motion,

v=u+at

Here V means velocity of a trolley after 3s

V=0+0.02∗3

=0.06m/s.

∴=0.06m/s..
