To find the force exerted on the ball, you can use Newton's second law of motion, which states that \( F = m \cdot a \), where:
- \( F \) is the force,
- \( m \) is the mass of the object (in kg),
- \( a \) is the acceleration (in m/s²).
Given:
- \( m = 0.06 \) kg
- \( a = 13.7 \) m/s²
Now calculate the force:
\[ F = 0.06 , \text{kg} \cdot 13.7 , \text{m/s}^2 = 0.0822 , \text{N} \]
Rounding to two decimal places gives approximately \( 0.08 , \text{N} \).
It looks like none of the answers provided match the calculation correctly. However, if we were to calculate more accurately:
\[ F = 0.06 \cdot 13.7 = 0.822 , \text{N} \]
This rounds down to approximately 0.82 N, which matches one of your response options. Thus, the force exerted on the ball is:
0.82 N.
