A battery-operated car utilizes a 12.0 V system. Find the charge (in C) the batteries must be able to move in order to accelerate the 790 kg car from rest to 25.0 m/s, make it climb a 1.80 ✕ 102 m high hill, and then cause it to travel at a constant 25.0 m/s by exerting a 5.40 ✕ 102 N force for an hour.
