A particle moves on a straight line OX so that its acceleration at time t is given by $\alpha=6t-24$ also when t=0, s=0 and v=45. find its velocity and displacement when t=5 seconds

2. anonymous

just intigrate alpha

3. anonymous

a=dv/dt put dv/dt=6t-24 dv=6tdt-24dt

4. anonymous

find v

5. anonymous

again v=dx/dt find x=displacement.

thanks :D
