Question

#14
which equation would be appropriate for the golfer to determine how hard to hit the golf ball?
a $f = ma$
b $a = \frac{(v_f - v_i)}{t}$
c $s = \frac{d}{t}$
d $p = mv$

Explanation:

Step1: Analyze each formula

• Formula \(F = ma\):
• \(F\) represents force, \(m\) is mass, and \(a\) is acceleration. Force determines how hard an object is hit.
• Formula \(a=\frac{(v_{f}-v_{i})}{t}\):
• This formula calculates acceleration (\(a\)) based on initial velocity (\(v_{i}\)), final velocity (\(v_{f}\)), and time (\(t\)). It does not directly relate to the "hardness" of hitting.
• Formula \(s = \frac{d}{t}\):
• \(s\) is speed, \(d\) is distance, and \(t\) is time. This formula is about speed calculation, not the force of hitting.
• Formula \(p = mv\):
• \(p\) is momentum, \(m\) is mass, and \(v\) is velocity. Momentum is not directly related to the force of hitting an object.

Answer:

A. \(F = ma\)
