Alistair is enjoying a tightly contested curling match. his team has just made a throw and their stone is approaching a stationary one, of identical mass, at a speed vo. after an elastic collision, his stone moves at an angle 0 relative to its original path. the initially stationary stone moves along an orthogonal direction. how fast is each stone moving?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° 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.)

When does your body conduct current more readily?
