Question

question 8 of 25
given the impulse acting on an object and the impact time, which equation
can be used to calculate the force applied to the object?

a. $f = \frac{\delta t}{i}$

b. $f = \frac{i}{\delta t}$

c. $f = i\delta t$

d. $f = \frac{1}{i\delta t}$

Explanation:

Step1: Recall Impulse Formula

Impulse \( I \) is defined as the product of force \( F \) and time interval \( \Delta t \), so \( I = F\Delta t \).

Step2: Rearrange for Force

To solve for \( F \), divide both sides of \( I = F\Delta t \) by \( \Delta t \). This gives \( F=\frac{I}{\Delta t} \).

Step3: Match with Options

Compare the derived formula with the options. Option B has \( F = \frac{I}{\Delta t} \), which matches.

Answer:

B. \( F=\frac{I}{\Delta t} \)
