1) A firefighter with a weight of 702 N slides down a vertical pole with an acceleration of 2.90 m/s2, directed downward. What are the magnitudes and directions (choose the positive direction up) of the vertical forces
(a) on the firefighter from the pole and
(b) on the pole from the firefighter?
2)Holding onto a tow rope moving parallel to a frictionless ski slope, a 63.1 kg skier is pulled up the slope, which is at an angle of 8.9° with the horizontal. What is the magnitude Frope of the force on the skier from the rope when
(a) the magnitude v of the skier's velocity is constant at 2.36 m/s and
(b) v = 2.36 m/s as v increases at a rate of 0.117 m/s2?
