An automobile traveling 80 mi/hr has wheels 31 inches in diameter. If the car is brought to a stop uniformly in 58 turns of the wheels, what is the magnitude of the angular acceleration of the wheels (in radians/second^2)?

Physics
A mass of 0.475 kg, on a frictionless table, is attached to a string which passes through a hole in the table. The hole is at the center of a horizontal circle in which the mass moves with constant speed. The radius of the circle is 0.510 m and the speed of the mass is 13.0 m/...

A 1.40 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as F = 3x^2 - 2x. If the block's speed passing through the origin was 3.80 m/s, with what speed (in meters/second) does it pass the point...

A block of mass 3.42 kg is drawn at constant speed a distance of 1.32 m along a horizontal floor by a rope exerting a constant force of magnitude 8.62 N and making an angle of 17.0 degrees above the horizontal. Compute the coefficient of friction between the block and the floor.
