A particle moving in a straight line covers half
the distance with speed of 3 m/s. The other hali
of the distance is covered in two equal time
intervals with speed of 4.5 m/s and 7.5 ms
respectively. The average speed of the partice
during this motion is
Answer:
4 total distance 4x
2equal time t
then avg speed=4x/2t+(2x/3)
