Answer :
Final answer:
The question is about finding the force required to accelerate a baseball in a high school physics context, but there's insufficient information to directly calculate this force. To find the acceleration, we'd use a kinematic equation, which could then be used to determine the force with Newton's second law if the mass is known.
Explanation:
The subject of this question is Physics, and it is typically suited for a High School grade level. The student is asking how much force is required to accelerate a 0.142 kg baseball to 44.7 m/s during a pitcher's 15-meter delivery. To solve this, we would need to use the formula for force based on Newton's second law of motion, F = ma, where 'F' is the force applied, 'm' is the mass of the baseball, and 'a' is the acceleration needed to reach the final velocity. However, given that the distance of the pitch is irrelevant to calculating the force directly and that we do not have the time duration of the acceleration, we cannot calculate the force without additional information. If instead, we were to find the acceleration given that the final velocity is 44.7 m/s and the distance over which the acceleration occurs is 15 m, we'd use the kinematic equation: v^2 = u^2 + 2as, where 'v' is the final velocity, 'u' is the initial velocity (assumed to be 0 m/s since the ball starts from rest), 'a' is the acceleration, and 's' is the displacement. Once we find 'a', we could then calculate the force using F = ma.
