) child is pulled along the flat ground on snow on a sled by his father. The child and sled together have a mass of 33 kg. The father pulls the sled by a rope 40 degree angle above the horizontal. If the coefficient of friction between the snow and the sled is. 16, determine the force the father must pull with to maintain constant velocity.

The fiqure shows a man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 78.4 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of 1.42 m/s2? (Hint: A free-body diagram can really help.) Problem continues below...
