6. A uniform building brick is pulled along rough ground by a force scale as shown in the diagram. [The mass of the brick is 2.5 kg] A. When the brick is pulled at constant speed the reading on the force scale is 8.2 N. Determine the force of friction between the brick and the ground. [A: Fp = 7.7 N] B. (i) Calculate the vertical component of the 8.2 N force. [A: Fx = 2.8 N] (ii) Determine the force that the ground [Normal Force] exerts on the brick and state the direction of this force. [A: F = 22.2 N upward (FN)]
