You have been accepted into a boat building competition. You get to pick between two boat plans. Boat A’s plans has the dimensions of 45m wide and 126m long and exerts 2300Pa of pressure. Boat B’s plans has the dimensions of 6m wide and 115m long and exerts 2700Pa of pressure. In order for the boat to float, the force applied to the water must not exceed 2.0 X 10 6 N. Would you pick Plan A or Plan B?
