A sled and rider have a total mass of 60.0 kg. They are on a snowy hill. The coefficient of kinetic friction between the sled and the snow is 0.150. The angle of the hill's slope measured upward from the horizontal is 24.0°. What is the acceleration of the rider? Is the acceleration greater, less than, or equal to your result if a more massive rider uses the same sled on the same hill? Explain.

A block is being pulled up an inclined plane by a force with magnitude F=45.0 N as shown In the figure above. The block has a mass of m =1.35 kg. The coefficient of kinetic friction between the block an the surface of the incline plane is µ = 0.287. The inclined plane makes an angle \theta= 31.7 degrees with respect to the horizontal. What is the magnitude of the acceleration of the mass?

The following information pertains to questions 1, 2, and 3. A workman pulls a sled across an asphalt road using a rope at angle 0 above the horizontal direction. The workman pulls with 1,000[N] of force. The coefficients of friction of the sled with the road are u=1.00 and µ=0.70. The sled has mass m. The sled is initially at rest. T710Q0[N]. 1) Which expression gives the magnitude of fmax for the situation illustrated above? A) mg B) mg – 1000cos(0) C) - mg + 1000cos(0) D) mg-1000sin(0) E) mg+ 1000sin(0) F) None of the above

An empty sled of mass 25 kg slides down a muiddy hill with a constant speed of 2.4 m/s The slope of the hill is inclined at an angle of 15 degrees with the horizontal. a. Calculate the frictional force on the sled as it slides down the slope b.Calculate the coefficient of friction between the sled and the muddy surface of the slope c. The sled reaches the bottom of the slope and continues of horizontal ground. Assume the same coefficient of friction. In terms of velocity and acceleration, describe the motion of the sled as it travels on horizontal ground.
