Two model railway wagons, X and Y, collide. At one instant, a force sensor shows that wagon X exerts a horizontal force of 1.2 N east on wagon Y. A student represents forces using a scale of 1.0 cm to represent 0.30 N.
Describe how the force exerted by wagon Y on wagon X should be represented by an arrow. Include a calculation.
