Question

an object travels 30m in 4s and then another 30m in 2s. calculate the average speed of the object under what condition is the magnitude of average velocity of an object equal to its average speed​

Answer 1

Answer:

10 m/ s

Explanation:

Total distance covered by the object = 30m+30m = 60m Total time taken = 4s+2s=6s Average speed=Total distance/Total time=60m/6s=10m/s.

1.(b)No, the above data is not sufficient to find the average velocity, since it is not given in which direction the distance is being covered. 2.(c)The magnitude of average velocity is equal to the magnitude of average speed, if the object is moving on a straight line and in the same direction.

Answer 2

Answer:

10 m/s

Explanation:

average speed= total path length/total time

here, average speed= 30+30/4+2

= 60/6

= 10m/s
