The final velocity of the ball when it is caught is 20.58 m/s
<h3>What is velocity?</h3>
Velocity is the rate of change of displacement.
To calculate the final velocity of the ball when it is caught, we use the formula below.
Formula:
- v = u+gt............ Equation 1
Where:
- v = Final velocity
- u = Initial velocity
- g = Acceleration due to gravity
- t = Time
From the question,
Given:
- u = 0 m/s
- g = 9.8 m/s²
- t = 4.2/2 = 2.1s
SUbstitute these values into equation 1
- v = 0+9.8×2.1
- v = 20.58 m/s
Hence, the final velocity of the ball when it is caught is 20.58 m/s
