Question

A van accelerates uniformly and its velocity changes from 5m/s to 25m/s in time't' .Find its average velocity (ans:15m/s) .....CLASS 9 PHYSICS: MOTION

Answer 1

v =v1+v2/2

=5+25/2=15m/s

Answer 2

Answer:

As we know average velocity is

(v1+v2)/2                                    

so

=(5 + 25)/2                                      

=15 m/s
