Two blocks are connected by a rope of negligible mass over a frictionless pulley. The mass of block A is 12.0 kg, and the coefficient of kinetic friction between block A and the incline is 0.25. Angle 8 of the incline is 25°. Block A slides down the incline at constant speed. (a) Draw the FBD of both blocks' >) What is the force exerted by the surface on the incline on block A? [ (c) What is the tension in the rope connecting the two blocks? ) What is the mass of block B? [₁ Assume the connecting rope has negligible mass. B

. A car is traveling at 50.0 km/h on a flat highway. (a) If the coefficient of friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop? (b) What is the stopping dis- tance when the surface is dry and the coefficient of friction is 0.600?

A carton of mass 35kg is at rest on a rough plane inclined at an angle of 25 degrees to the horizontal. Calculate the magnitude of the friction force, in Newton's, to 2 s.f. Take the magnitude of the acceleration due to gravity, g, to be 9.8 ms^-2

a block of mass "m" slides down an incline, which makes an angle of 30 degrees with horizontal. if the acceleration of the block is 3.3 m/s^2, then find the coefficient of kinetic friction
