Calculate the net acceleration of an object moving in a circle of radius 20 m if the object is moving at a constant speed of 15 m/s. Also calculate the net acceleration of the object when it speeds up from 15 m/s to 60 m/s in 5 seconds at the instant when its moving at 15 m/s and when it is moving at 60 m/s.
