please help I tried to do these questions but I keep getting them wrong.

Example 2-21 depicts the tollowing scenario with the accompanying figures. A hot-air balloon is rising straight upward with a constant speed of 6.5 m/s. When the basket of the balloon is 20.0 m above the ground, a bag of sand tied to the basket comes loose and reaches a maximum height of 22 m. Now we will consider some slightly different related scenarios to Example 2-21 . V PartA If the bag in Example 2-21 had been released at 300 m instead, with everything else remaining the same, would its maximum height be 32 m, greater than 32 m, or less than 32 m? ('2 32m 0 greater than 32 m (\"2 less than 32 m v PanB Find the speed of the bag in part A iust before it lands when it is released from 30.0 m. auest Answer v Part6 Now, suppose the balloon in Example 2-21 is descending with a constant speed of 4.2 m/s when the bag of sand comes loose at a height of 35 n1. What is the amount of time the bag is in the air? Express your answer using two significant figures.
