The tires of a 1545 kilogram car are 0.590 meter in diameter and the coefficients of friction with the road surface are µs = 0.800 and µk = 0.600. Assuming that the weight is evenly distributed on the four wheels, find the maximum torque that can be exerted by the engine on a driving wheel without spinning the wheel. If you wish, you may assume the car is at rest.
A 2.0kg block is projected down a plane that builds an angle of 20 degree with the horizontal with an initial kinetic energy of 2.0J.If the coefficient of kinetic friction among the block and plane is 0.40, how far (in meter) will the block slide dow..
