A high-speed railway car goes around a flat, horizontal circle of radius 480 m at a constant speed. The magnitudes of the horizontal and vertical components of the force of the car on a 65.0 kg passenger are 208 N and 637 N, respectively. (a) What is the magnitude of the net force (of all the forces) on the passenger? (b) What is the speed of the car?
Answers: 1
) = 208 N.
) = 637 N.
= 208 N.
where v is the velocity.
