A car starts from rest and moves around a circular track of radius 32.0 m

A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.600m/s2.

(a) What is the magnitude of its net linear acceleration 15.0 s later?
(b) What angle does this net acceleration vector make with the car’s velocity at this time?
