circular hoop, and then pass over a hump. Assume that friction and air resistance is
V6 - 9:90 m
/5=) 10.0M
A VA = ?
a. (5 points) To maintain contact with the rails, the car must have a speed of 9.90
m/s at point B (the top of the loop). Then what must the car's speed at point A
(bottom of the loop) have been, so that it will make the loop successfully?
b. (5 points) At the top of the hump at the end of the ride, the track has a radius of
curvature of 10.0 m. Having negotiated the loop successfully, using the speed you
calculated in the previous part, will the car stay in contact with the ride's rails as it
passes over the hump? Show a calculation that justifies your answer.
