Question

question 19 of 25 which equation can be used to calculate the time of impact when you have the impulse and force applied to an object? a. $delta t=\frac{i}{f}$ b. $delta t = fi$ c. $delta t=\frac{1}{if}$ d. $delta t=\frac{f}{i}$

Explanation:

Step1: Recall impulse - force - time relation

The impulse formula is $I = F\Delta t$, where $I$ is impulse, $F$ is force and $\Delta t$ is time of impact.

Step2: Solve for $\Delta t$

We can re - arrange the formula $I = F\Delta t$ for $\Delta t$. Dividing both sides of the equation by $F$ (assuming $F
eq0$), we get $\Delta t=\frac{I}{F}$.

Answer:

A. $\Delta t=\frac{I}{F}$
