You (m = 50 kg) are in a rollercoaster travelling at a constant speed of 50 mph when it goes over a hump which, at the top, can be approximated by a circle of radius 15 m. (A) Is the harness necessary in order for you to stay on the ride? In other words, if there was nothing keeping you in your seat, would you fly off? (B) If you answer to (A) is no, calculate the normal force at the top, if your answer to (A) is yes, calculate the force the harness must exert on you. (Remember that force is a vector so you have to indicate direction as well.) Hint for (A): 1. With what speed would you have to go over the hump in order for only gravity to be needed? 2. If your speed is larger, what do you think is going on?
