Question

1. A body rises vertically upward to a height of 100 m, in 5 seconds, then comes
back at the same position after another 5 s, what is the average speed and
average velocity of the body? *
O A. 20 km/h, 200 m/s
O B. 20 m/s, 0
O C. 200 km/h, 20 m/s
O D. 200 m/s, average velocity cannot be predicted​

Answer 1

Answer:

Answer 2

Answer:

b) 20m/s, 0

Explanation:

Av. Speed= Total Distance/Total Time= 200m/10s= 20m/s

Since displacement is 0, the velocity will be 0 too.
