Question

A particle starts from rest at t = 0 and moves in a straight line with acceleration as shown in figure. The velocity of the particle at t = 3 s is, 2 m s - 1, 4 m s - 1, 6 m s - 1, 8 m s - 1

MARKS App · Accepted Answer

Velocity at 3 s = total algebraic sum of area under the curve v ⁡ = 4 × 2 - 4 × 1 = 4 m/s
