A baseball has a mass of 145 g. A pitcher throws the baseball so that it accelerates at a rate of 80 m/s?. How much force did the pitcher apply to the baseball? (1 point)
• 65 N
• 11.6 Ng
• 0.6 N
• 1.8 N
The correct answer is:
• 11.6 N
To calculate the force applied to the baseball, you can use the formula:
Force = mass x acceleration
Given:
- Mass = 145 g = 0.145 kg (since 1 kg = 1000 g)
- Acceleration = 80 m/s²
Plugging in the values:
Force = 0.145 kg x 80 m/s² = 11.6 N
So, the force applied by the pitcher to the baseball is 11.6 N.
