1. A child (mass m) sits on a car seat which is accelerating
horizontally at 0.50g (where g is the acceleration of free fall).
What is the magnitude of the total force F exerted by the car
seat on the child?

2. Q2. Each diagram below shows three newton meters, in a two dimensional arrangement, joined to demonstrate a system of three forces acting at a point. The readings represent the magnitudes of the forces.
Which system of forces could be in equilibrium?
