Velocity-time equation of a particle moving in a straight line is v=2t-4 for t le 2s and v= 4-2t for 1 gt 2s. The distance travelled ( in meters) by the particle in the time interval from t=0 to t=4s is 4k. The value of 'k' is ( Here t is in second and v in m/s) :

Velocity-time equation of a particle moving in a straight line is v=2t

1.	Velocity-time equation of a particle moving in a straight line is v=2t-4 for t le 2s and v= 4-2t for 1 gt 2s. The distance travelled ( in meters) by the particle in the time interval from t=0 to t=4s is 4k. The value of 'k' is ( Here t is in second and v in m/s) :
