A small car with mass 0.650 kg travels at constant speed on the inside of a track that is a vertical circle with radius 5.00 m.
Q: If the normal force exerted by the track on the car when it is at the top of the track (point B) is 6.00 N, what is the normal force on the car when it is at the bottom of the track (point A)?
A car drives straight down toward the bottom of a valley and up the other side on a road whose bottom has a radius of curvature of 135 m. At the very bottom, the normal force on the driver is twice his weight.
- At what speed was the car traveling?
