A trolley going down an inclined plane has an acceleration of $2 cm s^{-2}$. What will be the velocity 3 seconds after the start?

Academic Physics NCERT Class 9

Given: $a= 2cm/s^2$ = $0.02m/s^2$

To find: Velocity 3 seconds after start

Solution:

We know, v = u + at

$v = 0 + 0.02 \times 3$

$= 0.06m/s$.
