Solve for Average Acceleration: 2) A plane starts accelerating with a zero fritial speed on a ruway for a period of 32 seconds and reaches a final speed of 288 km/hr, before it takes-of What is the average acceleration of a plane in m/s during its take-off time period? Solve for Free Falling Body: 3) An elevator manufacturing company for buildings is designing safety mechanisms shou their elevator's brakes fail during its operation, and it starts free falling downwards. Th company wishes to investigate the final velocity of the elevator when it reaches groun free falling so that they can build some safety mechanism. They release an elevator from a 4-story building's elevator chamber to fall freely, ead has an average height of 3.5 meters, elevator falls freely until it reaches the ground fl A) What will be the final velocity of the elevator when it reaches the ground. B) What is the elapsed time taken by the elevator to reach the ground from the pe it starts falling freely? Page 2 of 7
