A 3200 kg coaster car rolls along the frictionless track shown. To safely make it through the loop there is a minimum speed the coaster must have at the top of the loop. At this speed the normal force of the track pushing downward on the coaster is zero. The radius of the circular loop is 14.1 meters. At the top of the loop of radius 14.0 m the force of gravity is the only force acting on the coaster. What is the magnitude of the coaster's acceleration at the top of the loop?

What is the minimum coefficient of static friction ?sμs between the wall of the cylinder and the backs of the riders?
At an amusement park loop-the-loop ride, the loop has a radius of 10 m. In one of the cars, you are riding sitting on a scale, which measures your apparent weight (i.e., the normal force from the scale). Before the rides start, your apparent weight is 800 N. (a) What is your apparent weight at the top of the loop when the car is going 12 m/s? (b) What is your apparent weight at the bottom of the loop when the car is going 18 m/s?
A rollercoaster car starts at rest at some initial height h0 and then rolls down an incline. At the end of the incline is a loop of radius R = 10.4 m. Assuming that the car experiences negligible frictional forces, what is the minimum initial height (in m) that will ensure the car stays on the track at the top of the loop?
Chad gets on a roller coaster. Chad and the cart rolls down the frictionless loop with a constant speed of 7.4 m/s. The mass of Chad and the cart is 0.75 kg and the radius of the loop is 0.86 m.

You and your lab partner are conducting the Centripetal Force Lab with the goal of determining the mass of an unknown object as it travels in a circular path. Following the procedure perfomed in class and listed below, you attach your unknown mass to the string, run it through the PVC pipe and attach it to a known hanging mass of 350 g. You spin your unknown mass horizontally and determine an average period t= 0.286 s and a radius of the circular path r = 0.2 m.

A woman places her briefcase on the backseat of her car. As she drives to work, the car negotiates an unbanked curve in the road that can be regarded as an arc of a circle of radius 49.7 m. While on the curve, the speed of the car is 14.3 m/s at the instant the briefcase starts to slide across the backseat toward the side of the car. (a) What force causes the centripetal acceleration of the briefcase when it is stationary relative to the car? Under what condition does the briefcase begin to move relative to the car?(b) What is the coefficient of static friction between the briefcase and seat surface?
