Question

what is the average speed from 0s to 4s?​

Answer 1

Answer:

average speed = total/ total time.

Explanation:

a= v- u/t

a=0-0/4sec

a=0/4sec

a×4sec=0

a=4

2as=v²-u²

2×4×s=0

8×s=0

s=8

average speed=total distance / total time

average speed = 8/2

average speed= 4

Answer 2

Answer:

av speed= 0

Explanation:

bcoz Q has not define that the body is moving . so can consider that the body is not moving. u=0 ; v=0

av speed =(v+u)/(0+4)=(0+0)/(0+4)=0
