Velocity-time equation of a particle moving in a straight line is v = 2t - 4 for t ≤ 2 s and v = 4-2t for t> 2 s. The distance travelled by the particle in the time interval from t = 0 to t = 4 s is (Here, t is in second and v in m/s)
Velocity - time graph of the particle is as shown in figure
Magnitude of area of V - t graph is the distance travelled by the particle.
