3. Skydivers A and B are in a helicopter at 6400 ft above ground. Skydiver A jumps and descends for 4 seconds before opening her parachute. The helicopter then climbs to 7000 ft and hovers there. Forty-five seconds after A leaves the aircraft, B jumps and descends for 13 seconds before opening his parachute. Both skydivers descend at 16 ft/sec with the parachutes open. Assume that the skydivers fall freely (i.e. there is no effective air resistance) before their parachute opens.
