An object executes circular motion with constant speed whenever a net force of constant magnitude acts perpendicular to the velocity. What happens to the speed if the force is not perpendicular to the velocity?
A car of mass 1 230 kg travels along a circular road of radius 60.0 m at 18.0 m/s. (a) Calculate the magnitude of the cars centripetal acceleration. (b) What is the magnitude of the force of static friction acting on the car? (See Section 7.4.)
The Earth pulls on the Moon, and the Moon pulls on the Earth. However, the Earth is pulled more and less depending on what part of the Earth you consider. If the distance between the Earth and Moon is a, and the radius of the Earth is r then they are related by a = 64 r. Give the ratio of the acceleration on the near and the far side of the Earth from the Moon.
A 100-Kg car rounds a curve on a flat road of radius 50m at a speed of 15 m/s (54 km/h). Will the car follow the curve or will it skid? Assume: a-) the pavement is dry and the coefficient of static friction is 0.60 b-) the pavement is icy and the coefficient of static friction is 0.25
Question 2: #58 A curve at a racetrack has a radius of 800 m and is banked at an angle of 7.0°. On a rainy day, the coefficient of friction between the cars' tires and the track is 0.50. What is the maximum speed at which a car could go around this curve without slipping?
An oval racing track with curves of radius 2230 m that are banked at an angle of 23.0°. The size of the track allows for race cars to achieve speeds in excess of 500 km/h. An unintended consequence of the banked curves and high speeds is that race car drivers experience excessive G forces, especially in the "vertical" direction (with respect to their body position), causing dizziness and loss of consciousness. (a) A daring driver, pushing his car to the limit, experiences 5g of centripetal acceleration during one banking maneuver. What is the speed of his car during the maneuver? (Give your answer in km/h.) (b) If the driver is seated so that during the banking maneuver his upper body is aligned with the direction normal to the banked curve, what is the magnitude of the component of the centripetal acceleration along the driver's upper body? (Give your answer in terms of g.)

A bank curve on a highway is designed for traffic to move at 60km/hr. The radius of thecurve is 200m. If traffic was moving slower than the designed speed due to rain, at 40km/hr,what must be the minimum coefficient of friction between the tires and the road that would allow the car to stay on the road without sliding? Is this static of kinetic friction?
