A car with mass m = 1000 kg completes a turn of radius r = 650 m at a constant speed of v = 32 m/s. As the car goes around the turn, the tires begin to slip. Assume that the turn is on a level road, i. e. the road is not banked at an angle. Randomized Variables r = 650 m What is the numeric value of the coefficient of static friction, us, between the road and tires?

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
