Answer:The speed of the bag just before it reaches the ground is 21.71 m/s.Explanation:The speed of the bag can be found using the following equation:

Where:

is the final speed =?

is the initial speed = 7.7 m/s

g: is the gravity = 9.81 m/s²

y: is the height = 21 m

Therefore, the speed of the bag just before it reaches the ground is 21.71 m/s.I hope it helps you!
