A Roller Coaster Car Mass M 100 Kg Moves With A Constant Speed Of V 20 0 M S Around A Vertical Circular Loop Of Rad 2 (35.39 KiB) Viewed 70 times
A roller-coaster car (mass m= 100-kg) moves with a constant speed of v = 20.0-m/s around a vertical circular loop of radius R = 20.0-m as show in the Figure. Assume there is no friction between the car and the surface of the loop. Answer the following questions and find the normal force on the car at the top (upside down position) of the loop. R (a) [20%] What is the force direction of the loop onto the car when the car at this position? (b) (10%] How do you choose your reference reframe? (c) (30%) Write the equation(s) of the car when it is at the top of the loop. (d) (20%] Find the magnitude of the normal force. (e) [20%] Find the minimum speed must the car have so that it will just make it over the top without any assistance from the track.
