Answer :
Final answer:
The vertical velocity of the ball right before it hits the floor is 4.91 m/s.
Explanation:
To calculate the vertical velocity of the ball right before it hits the floor, we can use the equation:
Vertical velocity = √(2 * acceleration due to gravity * height)
In this case, the height is 99.4 cm = 0.994 m. Acceleration due to gravity is approximately 9.8 m/s². Plugging these values into the equation:
Vertical velocity = √(2 * 9.8 * 0.994) = 4.91 m/s
Therefore, the vertical velocity of the ball right before it hits the floor is 4.91 m/s.
