Answer:
The acceleration of the ball when it begins to move is 200 m/s²
Explanation:
The given parameters are;
The mass of the metal ball, m = 0.025 kg
The force exerted by the magnet on the ball, F = 5 N
From Newton's second law, F = m × a
Where;
a = The acceleration of the ball
Therefore, by substitution, we have;
5 = 0.025 × a
a = 5/0.025 = 200 m/s²
The acceleration of the ball when it begins to move = 200 m/s²
