After picking up passengers, a train accelerates uniformly until its speed is 100 km/hr at t= 300 s. If during this time it is traveling on a planar path that approximates the circle and line shown in the figure, find the magnitude of the train's acceleration when (a) t = 1 min and (b) t = 2 min.

I'm not sure what frame of reference to use and how to start this problem
normal acceleration is v^2/r
tangental acceleration is dv/dt
