Final answer:
The centripetal force acting on the ball with a mass of 0.04kg and accelerating at 43.2 m/s² is 1.728 Newtons.
Step-by-step explanation:
To find the centripetal force acting on the ball, we can use the following equation:
F = m × ac
Where:
- F is the centripetal force,
- m is the mass of the ball,
- ac is the centripetal acceleration.
Given:
- Mass of the ball, m = 0.04 kg,
- Centripetal acceleration, ac = 43.2 m/s².
Plugging in the numbers
F = 0.04 kg × 43.2 m/s²
F = 1.728 N
Therefore, the centripetal force acting on the ball is 1.728 Newtons.
