A roller coaster car is going over the top of a 16-m-radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60% of their true weight. How fast is the coaster moving?
Homework Answers
at the highest point due to his apparent weight , \
net weight = 100-60 = 40 % real weight = 0.4
now use a = g = V^2/r
V^2 = 0.4* 16 *9.8
V = 7.919 m/s

A huge spring launched a cart with passengers into a roller-coaster with a circular loop, which has a radius of 8.00 meters. The whole roller-coaster is frictionless. At the top of a circular loop, the cart is moving with a speed of 10.0 m/s. The total mass of the cart with the passengers is 450 kg. a. [5] With that speed, does the cart stay in contact with the roller-coaster at the top of the loop? b. [2] At the...
