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

OpenStudy (anonymous):

just intigrate alpha

OpenStudy (anonymous):

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

OpenStudy (anonymous):

find v

OpenStudy (anonymous):

again v=dx/dt find x=displacement.

thanks :D
