Question

if the velocity of a body changes from 13m/s to 30m/s while undergoing constant acceleration,what's the average velocity of the body?

1 Answer


  •        Average speed = (1/2) (beginning speed + ending speed)

                                   = (1/2)        ( 13 m/s  +  30 m/s )

                                   =    (1/2)        ( 43 m/s )

                                   =        21.5 m/s
