Question

A 0.04kg ball tied to a string moves in a circle that has a radius of 0.70 m. If the ball is accelerating at 43.2 m/s��, what is the centripetal force acting on the ball?

Answer 1

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.
