Ralph is standing at the edge of a 1.83 m diameter merry-go-round that is rotating at a rate of 2 rad/s. He walks to a point 0.3 m from the center of the merry-go-round. Calculate the angular velocity when he reaches that point. A teenager is not paying attention and doesn't see a traffic light turn red. They slam on their brakes. The coffee they are drinking spills onto the steering wheel. Use one of Newton's laws of motion to explain why the coffee spills when they slam on the brakes
