Q1. A helicopter is ascending vertically with a speed of 3.9 m/s. At a height of 115 m above the Earth, a package is dropped from the window. How much time does it take for package to reach the ground?

Q2. Jane and John, with masses of 51 kg and 66 kg, correspondingly, stand on a frictionless surface 13m apart. John pulls on a rope that connects him to Jane, giving Jane an acceleration of 0.9m/s2 toward him. If the pulling force is applied constantly, how far from John's starting position would they meet?
