Q1. A hot air balloon is rising straight up with a speed of 3.84 m/s. A ballast bag is released from rest relative to the balloon as it is 7.03 m above the ground. How much time elapses before the ballast bag hits the ground?

Q2. Two runners start simultaneously from the same point on the circular 200 m track and run in opposite directions. One runs at a constant speed of 6.14 m/s and the other runs at a constant speed of 5.43m/s. When they first meet, for how long a time will they have been running? When they first meet, how far will each one have run along track?
