QUESTION 6 A fun аctivity tо dо in Jоhаnnesburg is to bungee jump off the colourful Soweto Towers. Study the imаge and answer the questions. Right click on the button to open an image of a person bungee jumping off the Soweto Towers in a new window. 6.1 Identify two types of potential energy from the image. (2) 6.2 With reference to the image, what is the difference between these two types of potential energy? (2) 6.3 Explain the transfer of energy that takes place from when the person is stationary on the tower to when the person jumps off the tower. (3) 6.4 How would the height of the Soweto Towers affect the gravitational potential energy of the jumper? (3) 6.5 Calculate the jumper’s potential gravitational energy if the tower is 100 m high and the jumper has a mass of 75 kg. Use the equation: Egrav = mgh Remember that g = 9,8 m/s2 (4)
