Question

Abody covers one-third of the distance with a velocity 19. A partice moves in a straight line for 20 seconds

with velocity 3m/s and then moves with velocitu

4 m/s for another 20 seconds and finally moves

with velocity 5 m/s for next 20 seconds. What i

the average velocity of the particle?

(1) 3 m/s (2) 4 m/s (3)5 m/s (4) zero

20. An object travels 10 km at a speed of 100 m/s and

another 10 km at 50 m/s. The average speed over

v,the second one-third of the distance with a velocity V,and the last one-thid of the distance with a velocity Vg. The average velocity is ​
