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...

A roller-coaster car has a mass of 1040 kg when fully loaded with passengers. As the car passes over the top of a circular hall of radius 18 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative for the downward direction) on the car from the track if the car's speed is v = 7.4 m/s? (b) What is if v = 17 m/s? Use g = 9.81...

A roller-coaster car (mass = 988 kg including passengers) is about to roll down a track. The diameter of the circular loop is 21.5 m and the car starts out from rest 36.2 m above the lowest point of the track. Ignore friction and air resistance. X is the how high the car is= 36.2 m Y is the diameter of the loop= 21.5 m. What is the force exerted on the car by the track at the top of...

A roller coaster, loaded with passengers, has a mass of 2 500 kg; the radius of curvature of the track at the bottom point of the dip is 24 m. If the vehicle has a speed of 18 m/s at this point, what force is exerted on the vehicle by the track? (g = 9.8 m/s2) 2.3 x 104 N 4.7 x 104 N 5.8 x 104 N 7.3 x 104 N

A roller-coaster car has a mass of 498 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and- down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points and Bare parts of vertical circles of radius r1 = 10.0 m and r2 = 15.0 m, respectively. (a) If the vehicle has a speed of...

A roller-coaster vehicle has a mass of 504 kg when fully loaded with passengers (see figure). (a) If the vehicle has a speed of 20.0 m/s at point A, what is the force of the track on the vehicle at this point? (b) What is the maximum speed the vehicle can have at point B in order for gravity to hold it on the track? m/s
