A 1000 kg car moving at 7.0 m/s tries to round a corner in a circular arc of radius 9.0 m. The roadway is flat and level. (a) What size is the centripetal force that acts on the car as it successfully rounds the curve? (b) What is the minimum coefficient of friction between the tires and the road that will allow the car to make it through the turn without slipping?

An office door is given a sharp push and swings open against a pneumatic device that slows the door down and then reverses its motion. At the moment the door is open the widest, (a) does the doorknob have a centripetal acceleration? (b) Does it have a tangential acceleration?
A single bead can slide with negligible friction on a stiff wire that has been bent into a circular loop of radius 15.0 cm as shown in Figure P5.59. The circle is always in a vertical plane and rotates steadily about its vertical diameter with a period of 0.450 s. The position of the bead is described by the angle θ that the radial line, from the center of the loop to the bead, makes with the vertical. (a) At what angle up from the bottom of the circle can the bead stay motionless relative to the turning circle? (b) What If ? Repeat the problem, this time taking the period of the circle’s rotation as 0.850 s. (c) Describe how the solution to part (b) is different from the solution to part (a). (d) For any period or loop size, is there always an angle at which the bead can stand still relative to the loop? (e) Are there ever more than two angles? Arnold Arons suggested the idea for this problem. Figure P5.59

A 2000kg-car rounds a circular turn of radius 20m. If the road is flat and the coefficient of friction between tires and road is 0.7, how fast can the car go without skidding?
Consider that the car is making a flat circular curve with radius R = 230 m. Knowing that the friction coefficient between the tires and the road is = 0.960, determine the maximum speed with which the car can turn without sliding. Adopt: g = 10.0 m / s ^ 2.
Engineers who design roads typically “bank” (incline) curves in such a way that a car traveling at the recommended speed does not have to rely on friction between its tires and the road in order to round the curve. Suppose the radius of curvature of a road segment is 55 m, and the recommended speed is 45 km/hr. At what angle should the curve be banked?
Even though an object can have a constant tangential speed, the acceleration of an object in circular motion can NEVER be ____________________. A. zero B. less than the value of the speed C. equal to the value of the centripetal force.
