Paragraph Styles QUESTION 2 a) An object of mass 2 kg is launched at an angle of 30 above the ground with an initial speed of 40 m/s. Neglecting air resistance , calculate: i. the kinetic energy of the object when it is launched from the the ground. ii. the maximum height attained by the object . iii. the speed of the object when it is 12 m above the ground. (8 marks) b) According to a local scientist, a typical rain cloud at an altitude of 2 m will contain, on average, 3x10' kg of watervapour. Determine how many hours it would take a 2.5 kW pump to raise the same amount of water from the Earth's surface to the cloud's position. (3 marks) c) In Figure 1, two forces F, and F, act on a 5 kg object that is initially at rest. If the magnitude of each force is 10 N, calculate the acceleration produced. 60.09 Figure 1 (4 marks)
