2 Anglican High School 2023_S4_Prelim_Phy_P2 [Turn over Section A Answer all the questions in this section. 1 Ali throws an object vertically upwards from the top of his head. Fig . 1.1 shows the displacement-time graph of the motion of the object from the time it was released from the top of his head to the time it hits the ground. (a) Describe the motion of the object from time t = w seconds to t = y seconds in terms of its displacement and direction. …………………………………………………………………………………………………........ …………………………………………………………………………………………………........ …………………………………………………………………………………………………........ …………………………………………………………………………………………………... [2] (b) Using a letter “H”, mark and label a point in Fig. 1.1 which shows Ali’s height. [1] (c) In the space below, sketch a velocity-time graph of the object’s full motion. Assume air resistance is negligible. Label the area under the graph corresponding to the distance travelled clearly with the letters p, q, and/or p+q.
