Question

A trolley, while going down an inclined plane has an acceleration of $2cm{s}^{-2}$ what will be its velocity $3^s$ after the start?

Answer 1

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

Acceleration, $a=2cm{s}^{-2}=0.02m/s^2$

Time $t=3S$

As per 1st law of motion,

$v=u+at$

Here $V$ means velocity of a trolley after $3s$

$V=0+0.02\ast 3$

$=0.06m/s$.

$\therefore =0.06m/s$..
