A baseball has a mass of 145 g. A pitcher throws the baseball so that it accelerates at a rate of 80 m/s^2. How much force did the pitcher apply to the baseball?
a 0.6 N
b 1.8 N
c 65 N
d 11.6 N
To calculate the force, 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:
m = 145 g
a = 80 m/s^2
First, we need to convert the mass from grams to kilograms:
m = 145 g = 145/1000 kg = 0.145 kg
Now we can calculate the force:
F = 0.145 kg * 80 m/s^2
F = 11.6 N
Therefore, the force the pitcher applied to the baseball is 11.6 N. The correct answer is d) 11.6 N.
To find the force applied by the pitcher to the baseball, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration.
The mass of the baseball is given as 145 g, which is equivalent to 0.145 kg (since 1 kg = 1000 g).
The acceleration is given as 80 m/s^2.
Using the formula F = m * a, we can calculate the force:
Force (F) = mass (m) * acceleration (a)
F = 0.145 kg * 80 m/s^2
F = 11.6 N
Therefore, the force applied by the pitcher to the baseball is 11.6 N.
Hence, the correct answer is d) 11.6 N.
To find the force applied by the pitcher 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).
In this case, the mass of the baseball is given as 145 g. However, it's best to work with the mass in kilograms, so we need to convert grams to kilograms.
1 kg = 1000 g
Therefore, the mass of the baseball is 145 g / 1000 = 0.145 kg.
The acceleration is given as 80 m/s^2.
Using the formula F = m * a, we can plug in the values:
F = 0.145 kg * 80 m/s^2
F = 11.6 N
Therefore, the force applied by the pitcher to the baseball is 11.6 N. So the correct answer is option d - 11.6 N.
