K.C.S.E Physics Q & A - MODEL 1997PP2QN02

(a) Figure 2 shows a uniform plank 20 m long, weighing 400N resting on two supports A and B 9cm apart. A person weighing 600N walks towards B starting at

The data in the table below represents the upward force FA exerted at A as a function of distance, d. The distance d is measured from A

(i) On the grid provided plot a graph of FA ( y – axis) against the distance d
(ii) From the graph determine how far beyond point B, the person can walk before the plank tips
(b) In the set up in the figure 3, the metre rule is in equilibrium

Given that the metre rule is uniform, determine its weigh
