A curve of radius 30 m is banked so that a 950 kg car travelling at 40 km/h can go round it even if the road is so icy that the coefficient of static friction is approximately zero. You are commissioned to tell the local police the range of speeds at which a car can travel around this curve without skidding. Neglect the effects of air drag and rolling friction. If the coefficient of static friction is 0.3, what is...

1. A 1400 kg car goes around a corner with a radius of curvature= 60m. a) if the coefficient of static friction between the tires and the roads is 0.800 what is the maximum speed the driver can go before skidding. the curve is unbanked/flat. 2. A 2.40kg uniform rod of length of .750m rotates about its center. At t=0, its angular speed =2.50 rad/sec. It smoothly increases its rotation rate with an acceleration a=1.50 rad/s^2 a) what is its...

An elevator system in a tall building consists of a 800-kg car and a 950-kg counterweight joined by a light cable of constant length that passes over a pulley of mass 280 kg. The pulley, called a sheave, is a solid cylinder of radius 0.700 m turning on a horizontal axle. The cable does not slip on the sheave. A number n of people, each of mass 80.0 kg, are riding in the elevator car, moving upward at 3.00 m/s...
