Aproton travels at a speed of 2.0 × 106 meters/second. its velocity is at right angles with a magnetic field of strength 5.5 × 10-3 tesla. what is the magnitude of the magnetic force on the proton?

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.)
