Given
- Height = 10 m
- Time = 4 sec
To Find
- Final velocity
Solution
☯ v²-u² = 2as
- Assume initial velocity to be 0 m/s
━━━━━━━━━━━━━━━━━━━━━━━━━
✭ According to the Question :
⇒ v²-u² = 2as
- v = Final velocity = ?
- u = Initial velocity = 0 m/s
- a = Acceleration = 10 m/s²
- s = Displacement = 10 m
⇒ v²-0² = 2×10×10
⇒ v²-0² = 200
⇒ v = √200
⇒ v = 10√2 m/s
∴ The final velocity of the ball is 10√2 m/s
