Mary pushes a her sister down a hill in a cardboard box. The total mass of the box and child is 115 kg. The box starts at rest at the beginning of the incline. The hill is at an incline of 28 degrees with respect to the horizontal.The static and kinectic friction between the box and hill is ?? = 0.4 and ?? = 0.2. a. What is the magnitude of the friction force acting on the box?b. What is the magnitude of the net force acting on the box and child system?c. Will the block slide down the hill, or stay at rest?

Mazie stands on her kitchen floor. The coefficient of kinetic friction between her socks and the floor is 0.35, and the coefficient of static friction is 0.42. She has a mass of 58 kg. b. Mazie slides across the floor at a speed of 1.3 m/s. What is the force of kinetic friction acting on her? c. Mazie climbs up on the roof of her house, which has an angle of 25°. The coefficient of static friction between her and the roof is 0.35. Will she slip off the roof? Explain your answer. d. Given that μ s = 0.35, what is the maximum angle the roof could have without her slipping?

Two blocks are connected via a massless frictionless pully system. The hanging block is 3 kg. The other block is on a ramp of 25◦ and has a mass m. The coefficients of friction between the block on the ramp and the ramp are: µs = .8 and µk = .5. a. What is the minimum mass m that will not slip? b. If the minimum mass is nudged, it will start being pulled up the incline. What will the acceleration be when that happens?
