A body starts from origin and moves along x-axis so that its position at any instant is x=4t^2-12t where t is in second and v in m/s .what is the acceleration of particle

x=4t^2 - 12t
so the speed v = dx/dt
or, dx/dt= 8t -12
or, v= 8t-12
so the acceleration is a= dv/dt
or, dv/dt= 8
or, a= 8 unit.
as here t is in second and v is in m/s
so, a= 8 m/ sec^2
so the speed v = dx/dt
or, dx/dt= 8t -12
or, v= 8t-12
so the acceleration is a= dv/dt
or, dv/dt= 8
or, a= 8 unit.
as here t is in second and v is in m/s
