Question

a van accelerates uniformly at and its velocity changes from 5 M per second to 25 m per second in time T find its average velocity

Answer 1

In the case of uniform acceleration, average velocity, vav=(v1+v2)/2                                    

 =(5 + 25)/2                                      
=15 m/s

Answer 2

Answer:

Average velocity of car is 15 m/s

Explanation:

It is given that,

A van accelerates uniformly and its velocity changes from 5 m/s to 25 m/s in time t. We have to find its average velocity. It is defined as the sum of initial velocity and final velocity divided 2.

The mathematical relation for average velocity is given by :

$v_{avg}=\dfrac{v_i+v_f}{2}$

So, $v_{avg}=\dfrac{5\ m/s+25\ m/s}{2}$

$v_{avg}=15\ m/s$

So, the average velocity of the car is 15 m/s.
