Question

acen ( =f=a t=frac{d v}{d r} ),
inchal worky ( =u ) fund velruty ( =v )
( frac{d v}{d t}=a t )
( d v=a t d t )
Inleyrating both sides ( int_{u}^{v} d v=int_{0}^{t} d t d t )
Ansmer
( v-u=frac{a t^{2}}{2}+c )

# 7. The initial velocity of a particle (at t = 0) is u and the acceleration f of particle at time t is given by f = at. Where a is a constant which of the following relation for velocity v of particle after time t is true? (1) v = u + at? (2)v = u + at2/2 (3) v = u + at (4) none of these
