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?
• 11.6 N
• 65 N
• 1.8 N
• 0.6 N
11.6 N
11.6N
To find the force applied to the baseball, we can use Newton's second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a). In this case, the mass of the baseball is given as 145 g, which we can convert to kilograms by dividing by 1000 (since there are 1000 grams in a kilogram):
Mass (m) = 145 g / 1000 = 0.145 kg
The acceleration (a) is given as 80 m/s^2.
Now we can use Newton's second law to find the force (F):
F = m * a
F = 0.145 kg * 80 m/s^2
F = 11.6 N
Therefore, the force applied to the baseball is 11.6 N.
