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!
