which equation can be used to solve for acceleration?\no (t=\frac{delta v}{a})\no (v_f = at - v_i)\no (a=\frac{d}{t})\no (delta v=\frac{a}{t})
Answer
Explanation:
Step1: Recall acceleration formula
Acceleration $a$ is defined as the change in velocity $\Delta v$ over time $t$, i.e., $a=\frac{\Delta v}{t}$.
Step2: Analyze each option
- Option 1: $t = \frac{\Delta v}{a}$ can be rewritten as $a=\frac{\Delta v}{t}$ which is the correct formula for acceleration.
- Option 2: $v_f=at - v_i$ is a wrong - arranged form of the kinematic equation $v_f=v_i + at$.
- Option 3: $a=\frac{d}{t}$ is the formula for average speed ($v=\frac{d}{t}$), not acceleration.
- Option 4: $\Delta v=\frac{a}{t}$ is an incorrect rearrangement of the acceleration formula.
Answer:
$t = \frac{\Delta v}{a}$ (first option)
