Write your Name, Index number and Class in the spaces at the top of this page. Write in dark blue or black ink. You may use an HB soft pencil for any diagrams or graph. Do not use staples, paper clips, glue or correction fluid. Section A: Answer all the questions in the spaces provided. Section B: Answer only one of the two questions from this section. Candidates are reminded that all quantitative answers should include appropriate units. The use of an approved scientific calculator is expected, where appropriate. Candidates are advised to show all their working in a clear and orderly manner, as more marks are awarded for the sound use of Physics than for correct answers. At the end of the examination, fasten all your work securely together. The number of marks is given in the brackets [ ] at the end of each question or part question.

It hits the ground with a velocity of +6.0 m/s. The acceleration due to gravity is 10.0 m/s2. (a) Calculate the time taken for the ball to hit the ground after the student drops it. time taken = ………………….. [2] (b) The ball bounced immediately without loss of energy. The ball reaches back to its original height before it was caught by the student. On Fig. 1.1, draw the velocity-time graph for the ball. [2] (c) Calculate the height at which the rubber ball was released. height = ………………….. [2] 0 time / s Fig. 1.1 m / s velocity [Total:6]
