Answer :
The ball's velocity after it has travelled a total distance of 50.0 meters is 40.63 m/s
Data obtained from the question
The following data were obtained from the question:
- Initial velocity (u) = 25.9 m/s
- Acceleration due to gravity (g) = 9.8 m/s²
- Height (h) = 50 m
- Final velocity (v) = ?
How to determine the final velocity
We can obtain the final velocity as illustrated below:
v² = u² + 2gh
v² = 25.9² + (2 × 9.8 × 50)
v² = 670.81 + 980
v² = 1650.81
Take the square root of both sides
v = √1650.81
v = 40.63 m/s
Thus, the velocity after travelling 50 m is 40.63 m/s
