Determining the Force Normal on a Toy Car moving up a Curved Hill (5:06)

A 0.453 kg toy car moving at 1.15 m/s is going up a semi-circular hill with a radius of 0.89 m. When the hill makes an angle of 32° with the horizontal, what is the magnitude of the force normal on the car? This is an AP Physics 1 topic.
