The centripetal acceleration is #=25ms^-2# and the tangential acceleration is #=0ms^-2#

The speed of the car is #v=100ms^-1#

The radius of the track is #r=400m#

The angular velocity is #omega=v/r=100/400=0.25rads^-1#

The angular acceleration is #alpha=0rads^-2#

The tangential acceleration is #a_T=alphar=0*400=0ms^-2#

The centripetal acceleration is #a_C=v^2/r=100^2/400=25ms^-2#
