Engineering a highway curve. If a car goes through a curve too fast, the car tends to slide out of the curve. For a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the force is directed down the bank (in the direction water would drain). Consider a circular curve of radius R = 270 m and bank angle 9, where the coefficient of static friction between tires and pavement is us. A car (without negative lift) is driven around the curve as shown in Figure (a). Find an expression for the car speed Vmax that puts the car on the verge of sliding out, in terms of R, 8, and us. Evaluate Vmax for a bank angle of 0= 11° and for (a) μ = 0.48 (dry pavement) and (b) us= 0.043 (wet or icy pavement). (Now you can see why accidents occur in highway curves when icy conditions are not obvious to drivers, who tend to drive at normal speeds.)

A 55.2 kg ice skater is moving at 4.07 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.805 m around th pole. (a) Determine the force exerted by the horizontal rope on her arms. (b) Compare this force with her weight by finding the ratio of the force to her weight.
A ball of mass m is suspended on a light string of length l from the ceiling. The ball is then put into motion such that it rotates in a horizontal circle with a rotation rate of w ( rad/s). Notice that the string makes an angle of with respect to the vertical during this motion. 1) find the tension in the string and the angle. 2) if the ball moved at twice it's first rotation rate, find the new angle the string would make with respect to the vertical. c) find the tension in the string at this new rotation rate. 6) how much faster is the ball speed with this new rotation rate as compared to the oroginal speed? Find a ration of the two speed.

A student spins a rubber stopper, tied to a string, over his head in a horizontal circle. The radius of the circle is, r, meters and the stopper has a mass of, m, grams. The stopper has period of, T, seconds, which results in a tension, 6.3 N. If the radius of the swing was changed by a factor of 2.4, what would be the resulting tension? Give your answer to 3 sig figs (1 decimal place in this case)
Problem 1. What is the maximum speed with which a 2,000-kg car can round a turn of radius 75.0 m on a flat (horizontal) road if the coefficient of static friction between the tires and the road is 0.600? What angle should the turn be banked to keep the car on the bank at this speed if the coefficient of static friction is changed to 0 (an iey curve)?
