Wo stationary positive point charges, charge 1 of magnitude 3.35 nc and charge 2 of magnitude 1.55 nc , are separated by a distance of 58.0 cm . an electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. what is the speed vfinal of the electron when it is 10.0 cm from charge 1?
express your answer in meters per second.

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.)
