What force is needed to give a 4.5-kg bowling ball an acceleration of 9 m/s2?

Question

Question 2 options:

0.5 N

2 N

40.5 N

36.5 N

Answer 1

To find the force needed to give a bowling ball an acceleration, we can use Newton's second law of motion, which states that \( F = ma \), where \( F \) is the force, \( m \) is the mass of the object, and \( a \) is the acceleration.

Given:

• Mass \( m = 4.5 , \text{kg} \)
• Acceleration \( a = 9 , \text{m/s}^2 \)

Now, we calculate the force:

\[ F = m \cdot a = 4.5 , \text{kg} \cdot 9 , \text{m/s}^2 = 40.5 , \text{N} \]

So the force needed is 40.5 N. The correct option is:

40.5 N
