Question 5: (a) It is proposed to use artillery to deliver SO2 to the stratosphere (20 km height). Shells will be fired vertically at an initial velocity of 800 m/s. Once they reach their maximum altitude, they will release their payload of SO2, then fall to the ground. Calculate the maximum altitude reached by the shells, showing whether the aim of the project has been met [15 marks) The following data are provided with regard to each shell: Mass with payload: 2000 kg Diameter: 0.5 m Drag coefficient 0.5 Assume air to be of constant density =0.8 kg/m². (b) For the following: i. Ocean Acidification ii. Biodiesel iii. Accelerated Weathering In the context of Engineering Design and the Natural Environment, what do you understand by the term? Write a concise paragraph explaining the meaning in each case, including chemical equations where appropriate. [6 marks each]
