For the different values given for the radius of curvature RRR and speed vvv, rank the magnitude of the force of the roller-coaster track on the cart at the bottom of each dip. Rank from largest to smallest. To rank items as equivalent, overlap them. A) R = 60m v = 16 m/s
B) R = 15m v = 8m/s
C) R = 30m v = 4m/s
D) R = 45m v = 4m/s
E) 30m v = 16 m/s
F) R = 15m v =12 m/s

Explanation:

The force of the roller-coaster track on the cart at the bottom is given by :

, m is mass of roller coaster

Case 1.

R = 60 m v = 16 m/s

Case 2.

R = 15 m v = 8 m/s

Case 3.

R = 30 m v = 4 m/s

Case 4.

R = 45 m v = 4 m/s

Case 5.

R = 30 m v = 16 m/s

Case 6.

R = 15 m v =12 m/s

Ranking from largest to smallest is given by :

F>E>A=B>C>D

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
