43. A snow skier of mass 85.0 kg slides with constant velocity down a slope that makes an angle of 10.0° with the horizontal. (a) What is the coefficient of sliding friction? (b) If the slope increases to 15.0° what will be the skier’s rate of acceleration?

3. (a) A 1700 kg car is parked on a road that rises 18° above the horizontal. What are the magnitudes of (i) the normal force and (ii) the static frictional force that the ground exerts on tires? (b) A 52.5 kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.678 and 0.283, respectively. What horizontal pushing force is required to (i) just start the crate moving and (ii) slide the crate across the dock at a constant speed?

QHQBP A(n) 11 kg mass is on an incline, with a = 4.7_m and b = 2.3_m. The coefficient of kinetic friction between the mass and the surface of the incline is k = 0.38. If the mass is initially near the top of the incline and sliding down, then what is the mass's acceleration down the incline? m b 16. 0.9627_m/s² 1.041_m/s² 1.103 m/s² A. B. C. 1-1 a D. E. F. 1.137 m/s² 1.01 m/s² 1.073_m/s²

While loading furniture into a truck, you push a 1.56 kg chair up a 14.7 degree ramp, with a horizontal force of 12.1 N. How long does it take to reach a speed of 4 m/s, starting from rest? The coefficient of kinetic friction chair - ramp is 0.345.
