Question

# A particle is moving in a straight line with constant acceleration '$$a$$' and initial velocity $$v_0$$. Average velocity during first $$t$$ second is _____

A
v0+12at
B
v0+at
C
v0+at2
D
v02

Solution

## The correct option is A $$v_0 + \dfrac{1}{2}$$atInitial velocity $$= v_0$$Acceleration $$= a$$Time $$= t$$Distance moved $$= v_0t + \dfrac{1}{2} at^2$$Average velcoty $$= \dfrac{distance}{time}$$$$= \dfrac{v_0t + \dfrac{1}{2} at^2}{t}$$$$= v_0 + \dfrac{1}{2}at$$Physics
