Review Example 5, which deals with the bobsled in Figure 5.5. Also review Conceptual Example 4. The mass of the sled and its two riders in Figure 5.5 is 152 kg. Find the magnitude of the centripetal force that acts on the sled during the turn with a radius of (a) 33.0 m and (b) 24.0 m. Figure 5.5 (a) Number (b) Number Units Units <

An engineer is trying to determine the speed at which a car can travel around a curved race track without using any friction, Assume the car does not move up or down the incline and completes a horizontal circle. Complete all calculations under these circumstances. Hint: Use the variable m for the mass of the car, it will cancel! number of forces in plane: centripetal force: 340m Are all forces balanced? 160 What is the magnitude of the centripetal acceleration? unit At what speed does the car need to travel? unit finalize check answers cannot be determined (after completing ALL problems) Unit 10: circular motion, challenge Desmos Scientific Online Calculator hp esc HAAR @ #3 2$ & 96

Ch3qrt # 1 ,A carousel has a radius of 12.0 m and turns once in 45.0 s. What is the speed of a rider on the edge of the carousel?#2 An airplane with a mass of 800 kg is flying in a circle of radius 500 m at 50 m/s. What is the centripetal force required to keep the airplane flying in the circle?#3 You are on a subway holding yourself off the floor by pulling on an overhead rail. The subway starts moving, and your body makes an angle of 20.0° with the vertical. Determine the acceleration of the subway car.

Two banked curves have the same radius. Curve A is banked at 13.9 °, and curve B is banked at an angle of 18.1 °. A car can travel around curve A without relying on friction at a speed of 13.7 m/s. At what speed can this car travel around curve B without relying on friction?
