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)
A. 65 N
B. 1.8 N
C. 11.6 N
D. 0.6 N
The force applied to the baseball can be calculated using Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a), or F = m x a.
Using this formula, we can calculate the force applied to the baseball as:
F = 0.145 kg x 80 m/s^2
F = 11.6 N
Therefore, the correct answer is C. 11.6 N.
Well, the baseball sure got a nice acceleration there! But let's calculate the force the pitcher applied. To do this, we can use Newton's second law, which states that force equals mass times acceleration.
So, F = m*a. Plugging in the values, we get F = 0.145 kg * 80 m/s² = 11.6 N.
So, the answer is C. 11.6 N. And the pitcher definitely gave it a good toss!
To calculate 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.
Given:
Mass of the baseball (m) = 145 g = 0.145 kg
Acceleration of the baseball (a) = 80 m/s^2
Using the formula for force (F = m * a), we can substitute the given values:
F = 0.145 kg * 80 m/s^2
Calculating the force:
F = 11.6 kg*m/s^2
Since the unit of force is Newton (N), we can convert kg*m/s^2 to N:
1 N = 1 kg*m/s^2
Therefore, the force applied by the pitcher to the baseball is approximately 11.6 N.
The correct answer is C. 11.6 N
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 the mass (m) of an object multiplied by its acceleration (a), or F = m * a.
First, we need to convert the mass of the baseball from grams to kilograms, since the SI unit of mass is kilograms. There are 1000 grams in a kilogram, so the mass of the baseball is 145 g / 1000 = 0.145 kg.
Next, we can calculate the force applied by multiplying the mass and the acceleration: F = 0.145 kg * 80 m/s^2 = 11.6 N.
Therefore, the force applied to the baseball by the pitcher is 11.6 N.
So, the correct answer is C. 11.6 N.
