A 170. Lb. person is in crutches. Each crutch makes an
angle of 22.0° with the vertical. Half of the person's
weight is supported by the crutches, the other half by
the vertical forces exerted by the ground onto his feet.
Assuming that he is at rest and that the force exerted
by the ground on the crutches acts along the crutches,
determine (a) the smallest possible coefficient of
friction between crutches and ground, and (b) the
magnitude of the compression force supported by
each crutch.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
