Answer question one please, thank you :)

Essential formulae FORMULAE to be used Gravitational Force: F. = mg (always downward) Normal Force: FN = mg (always positive and is perpendicular to the plane) Frictional Force: Efric = HEN Net Force: FNet = ma OR FNet = Eapp + Efric Force applied: Fapp = FNet - Efric Acceleration: a = FNet/m Coefficient of Friction u (no sign and unit) = Efric/F 1.) TWO PEOPLE are paddling together in a canoe. EACH PERSON exerts a 4 horizontal force of 238 [N] toward the back of the canoe. What is the NET HORIZONTAL FORCE on the canoe? *
