Figure 1 At position C, the ball has just left the tennis player’s hand at a speed of 5.0 m/s The tennis ball has a mass of 0.058 kg 0 1 . 1 Write down the equation that links kinetic energy, mass and speed. [1 mark] 3 SPECIMEN MATERIAL Turn over ► IB/M/SAMs2/8463/1H Do not write outside the box 0 1 . 2 Calculate the kinetic energy of the tennis ball at position C. [2 marks] Kinetic energy = J 0 1 . 3 At position A the tennis ball is at maximum height. What is the gravitational potential energy of the tennis ball at position A? Ignore the effect of air resistance. [1 mark] At position B the tennis ball has 0.38 J of gravitational potential energy. 0 1 . 4 Write down the equation that links gravitational field strength, gravitational potential energy, height and mass. [1 mark] 0 1 . 5 Calculate the height of the tennis ball above the tennis player’s hand when at position B. gravitational field strength = 9.8 N/kg [3 marks] Height = m 8 4 SPECIMEN MATERIAL IB/M/SAMs2/8463/1H Do not write outside the box 0 2 The wind turbines in a wind farm must have a minimum distance of 500 m between them for maximum efficiency. Figure 2 shows the position of nine wind turbines in a wind farm. Figure 2 0 2 . 1 Suggest one way in which the layout of this wind farm ensures maximum efficiency when the wind direction changes.
