- 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 car is trying to make a turn on a banked curve on a very icy day and the frictional force between the tires and road is zero. The curve has a radius of 50 m and the car is moving at 12 m/s. What angle should the curve be banked at for this to happen safely?
- 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?A 1250 kg car traveling at a speed of 25.0 m/s rounds a 175 m radius curve. Assuming that the curve is banked and the road is frictionless, determine the bank angle with respect to the horizontal.
