Velocity time equation of a particle moving in a straight line is v=2t−4 for t≤2s and v=4−2t for t>2.The distance travelled by the particle in the time interval from t=0 to t=4s is (Here t is in second and v in m/s) Average velocity of a particle moving in a straight line with constant acceleration a and initial velocity u in first t seconds is.
