A baseball has a mass of 145 g. A pitcher throws the baseball so that it accelerates at a rate of 80 m/s2. How much force did the pitcher apply to the baseball?(1 point) Responses 0.6 N 0.6 N 1.8 N 1.8 N 11.6 N 11.6 N 65 N

Answer 1

To find the force applied to the baseball, 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,
• \( a \) is the acceleration.

Given:

• The mass \( m = 145 \) g = \( 0.145 \) kg (since 1 kg = 1000 g),
• The acceleration \( a = 80 \) m/s².

Now, plug the values into the equation:

\[ F = 0.145 , \text{kg} \cdot 80 , \text{m/s}^2 \]

Calculating this:

\[ F = 0.145 \times 80 = 11.6 , \text{N} \]

Thus, the force applied to the baseball is 11.6 N.
