A billiard ball is moving initially at 16m/s and is accelerating at -2m/s^2. The ball travels 4m. What is the final velocity of the ball

Answer :

LAMMETTHASHGO

Assuming constant acceleration, if v is the final velocity of the ball, then

v ² - (16 m/s)² = 2 (-2 m/s²) (4 m)

v ² = 240 m²/s²

v ≈ 15.5 m/s
