The graph in Figure 1 shows the motion of an oscillator which moves upand down. The upwards direction is taken as being positive.4. (a) At time t= 0 s, the oscillator is in a central position.For each of the points (i), (ii), (iii) and (iv) say whether the oscillator is moving up or down, or if it stationary. If the distance travelled by the oscillator in the first 2 seconds is5.0 m, determine the displacement of the oscillator after 10 sassuming that its motion is a perfectly repeating cycle.Explain your answer.13 marks)
