(Consider that east goes in the direction of the + x axis and that north goes in the direction of the + y axis.) a) What is the magnitude of the net force (in N) on the object? b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the + x axis)A firefighter with a weight of 779 N slides down a vertical pole with an acceleration of 3.11 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? (a) Number i Units (b) Number i UnitsSuppose you are at a bowling alley, where a machine uses a constant force and pushes balls up a ramp one meter in length. The balls are sliding -- not rolling -- along the incline, and they end up half a meter above the base of the ramp. Ignore friction. Approximately how much force does the machine put on a 5 kg bowling ball? 1.0 m H 0.5 m 200 N 50 N 25 N O 5N Impossible to determine
