A trolley while going down an inclined plane, has an acceleration of 2

1.	A trolley while going down an inclined plane, has an acceleration of 2 cm s(power -2).What will be its velocity 3s after the start?
Answer» olley has an acceleration a = 2 cm / sec² down the INCLINED plane. its initial velocity is U = 0 m/sec. as it STARTS from rest. v = u + a t = 0 + 2 * t = 2 * 3 = 6 m /sec this velocity is along the inclined plane direction.we need to specify the direction as velocity is a vector quantity.
