(a(i))[2]
Calculate the resultant horizontal force on the boat in Fig. 3.1 and state its direction. The diagram shows 80 N acting backwards and 200 N acting forwards on the boat.
(a(ii))[1]
Suggest what causes the 80 N force on the boat in Fig. 3.1.
(a(iii))[1]
A different boat is moving and the horizontal forces acting on it are balanced. Describe the horizontal motion of this boat.
(b)[4]
Calculate the moment of the 60 N force about the pivot. Include the unit.
