A car of mass M = 1500 kg traveling at 55.0 km/hour enters a level turn...
A car of mass M = 1500 kg traveling at 55.0 km/hour enters a level turn (θ=0), and there is a coefficient of static friction μ between the road and the car's tires. What is μmin, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 55.0 km/hour and that the radius of the curve is 65.4 m .

A car of mass M = 800 kg traveling at 55.0 km/hour enters a
banked turn covered with ice. The road is banked at an angle ?, and
there is no friction between the road and the car's tires as shown
in(Figure 1) . Use g = 9.80 m/s2 throughout this problem.
Now, suppose that the curve is level (?=0) and that the ice has
melted, so that there is a coefficient of static friction ? between
the road and...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
