A small button placed on a horizontal rotating platform with diameter 0.530 m will revolve with the platform when it is brought up to a speed of 43.0 rev/min, provided the button is no more than 0.230 m from the axis. What is the coefficient of static friction between the button and the platform? How far from the axis can the button be placed, without slipping, if the platform rotates at 63.0 rev/min ?

A block is placed on a turntable 43 cm from the axis of rotation. The turntable very slowly speeds up to 35.5 RPM. What is the minimum coefficient of static friction between the block and the turntable surface that would prevent the block from sliding away under these conditions?

A roller coaster has a vertical loop of radius 25.0 m. If the roller coaster operates at a constant speed of 30.0 m/s while in the loop, what normal force does the seat provide for a 60 kg passenger at the bottom of the loop? O 2775 N 2748 N O 588 N O 1305 N ) 1572 N O 2160 N

A man riding a bicycle with a 100 kg total mass is performing horizontal circles on flat track. If the coefficient of static friction between the tires and track is 0.600, find the smallest radius the man can make when travelling at a speed of 10.0 m/s.

A 693 kg car traveling at 32.8 m/s is going around a curve having a radius of 105.5 m that is banked at an angle of 26.4°. The coefficient of static friction between the car's tires and the road is 0.600. What is the magnitude of the force exerted by friction on the car?

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 car rounds an unbanked (level) curve of radius 76 m. If the coefficient of static friction between the road and car is 0.56, what is the maximum speed at which the car traverses the curve without slipping? V= Question Help: m/s Submit Question Hint 1 Read

A case of fine glassware is loaded into a truck and sits on the floor. The truck drives along a street that follows along a circle that has a radius of 30.5 meters. The street is not banked. The coefficient of static friction between case of glass and the floor of the truck is 0.570. If the truck drives too fast, the case of glassware will slip and the glass will be damaged. How fast can the truck be moving without the box sliding?
