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?
To find the force applied to the baseball, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
F = m * a
Given that the mass of the baseball is 145 g, or 0.145 kg, and the acceleration is 80 m/s, we can substitute these values into the formula:
F = 0.145 kg * 80 m/s
Calculating the product gives:
F = 11.6 kg * m/s
Therefore, the pitcher applied a force of 11.6 kg*m/s to the baseball.
