To find the force exerted on the ball, you can use Newton's second law, which states:
\[ F = m \cdot a \]
where:
- \( F \) is the force,
- \( m \) is the mass of the object (0.06 kg),
- \( a \) is the acceleration (13.7 m/s²).
Now, substituting the values:
\[ F = 0.06 , \text{kg} \cdot 13.7 , \text{m/s}^2 \]
\[ F = 0.822 , \text{N} \]
Rounding this to two decimal places gives approximately:
\[ F \approx 0.82 , \text{N} \]
Therefore, the correct answer is:
0.82 N
