Problem
A swimmer starts from the origin O(0,0) of a rectangular swimming pool and reaches the springboard located at P(12m,5m).
(a) Find the components of the displacement vector OP.
(b) Calculate the magnitude of this displacement and express it correct to one decimal place.
(c) Determine the angle that OP makes with the positive x–axis, giving the answer in degrees correct to the nearest whole number.
(d) If the swimmer had instead first reached the point Q(12m,0) and then moved to P, compute the total distance covered and compare it with the magnitude found in part (b).
