- .A curve in a stretch of highway has radius 512 m. The road is unbanked. The coefficient of static friction between the tires and road is 0.700. When the car enters the curve at a speed greater than the maximum safe speed (speed at which the car won’t skid), which of the following statements are correct?A vial containing a blood sample is placed into a centrifuge, which spins the sample quickly to separate the blood into its parts. The centrifuge has a radius of 0.12 m, and spins at a rate of 1750 rpm. If the blood sample and vial have a combined mass of 95 g, what is the centripetal force holding the vial in place? 22.0 N 991 N 4030 N 383 N
- You have a horizontal grindstone (a disk) that is 87 kg, has a 0.31 m radius, is turning at 94 rpm (in the positive direction), and you press a steel axe against the edge with a force of 23 N in the radial direction. The kinetic coefficient of friction between steel and stone is 0.20. What is the number of turns, N, that the stone will make before coming to rest?A car drives around a curve with radius 400 m at a speed of 32 m/s. The road is banked at 7.0 degree. The mass of the car is 1500 kg. What is the magnitude of the centripetal force in order to make this turn? I am given an answer of 3800N, but not quite sure how to get there. Thanks!A van with mass m = 1000 kg is driving around a circular curve of radius r = 950 m when it begins to rain. The coefficients of static friction between the track and tires is μd = 0.59 when dry and μw = 0.17 when wet. Write an expression for the maximum magnitude of the force of static friction Ff acting on the van if μs is the coefficient of friction. What is the maximum tangential speed that the van can take the corner at without slipping when dry in m/s? What is the maximum tangential speed when wet in m/s?
- The peripheral speed of the tooth of a 10-in.-diameter circular saw blade is 150 ft/s when the power to the saw is turned off. The speed of the tooth decreases at a constant rate, and the blade comes to rest in 9 s. Determine the time at which the total (or resultant) acceleration of the tooth is 130 ft/s?.A road with a radius of 75.0 m is banked so that a car can navigate the curve at a speed of 16.8 m/s without any friction. When a car is going 36.8 m/s on this curve, what minimum coefficient of static friction is needed if the car is to navigate the curve without slipping?A 2 m rope attaches a tire to an overhanging tree limb. A boy swinging on the tire has a tangential speed of 2.2 m/s. If the magnitude of the centripetal force is 90 N; what is the boy mass?
- You are swinging a 0.45 kg water balloon vertically. The distance from your shoulder (acting as the center of rotation) and the water balloon is about 0.70 m. You estimate the water balloon is traveling at 6.0 m/s. At the very bottom of the circular path, how much force is your hand holding the water balloon?Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B is full. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is µs. The speed of the turntable is gradually increased. Describe what will happen. Include which container will fall off first or if they will fall off at the same time.
