To calculate the force needed to accelerate an object, you can use Newton's second law of motion, which states:
\[ F = m \cdot a \]
where:
- \( F \) is the force,
- \( m \) is the mass of the object,
- \( a \) is the acceleration.
In this case:
- \( m = 25 \, \text{kg} \)
- \( a = 2 \, \text{m/s}^2 \)
Now plug the values into the formula:
\[ F = 25 \, \text{kg} \cdot 2 \, \text{m/s}^2 \]
\[ F = 50 \, \text{N} \]
None of the provided answers (5N, 100N, 12.5N) are correct. The force needed to accelerate the 25kg bowling ball at 2m/s² is 50N.
