Question: 2. Use the position-time graph below to calculate the velocity for the object during parts A, B and G (3 marks) 100.0 D E 80.0

2. Use the position-time graph below to calculate the velocity for the object during parts A, B and G (3 marks) 100.0 D E 80.0 F 60.0 Displacement (m) B 40.0 G A 20 0 2 4 6 8 10 12 14 16 18 20 22 24 Time (s) 3. A skydiver jumps out of a plane and accelerates towards the Earth. Assuming there is no air resistance, determine: a. How far the skydiver has fallen after 20 seconds. (2 marks) b. . The sky diver's velocity at this point. (2 marks) 4. A plane is travelling at 280km/h when it touches ground for landing. As this happens the pilots immediately apply all mechanisms to slow the plane. If it takes 42 seconds to reach 5km/h, calculate the acceleration of the plane. (2 marks)
