A175 g ball containing 4.20×10^8 excess electrons is dropped into a 120 m vertical shaft. at the bottom of the shaft, the ball suddenly enters a uniform horizontal 0.200 t magnetic field directed from east to west. part a: if air resistance is negligibly small, find the magnitude of the force that this magnetic field exerts on the ball just as it enters the field.
part b: if air resistance is negligibly small, find the direction of the force that this magnetic field exerts on the ball just as it enters the field. (north, east, south, west)

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?
