If a falling rock undergoes a Delta v of 112(m)/(s) due to an bar (a) of m/s^2 how long did it fall? a 11.4 seconds b 3.5 seconds C 9.8 seconds d 6.7 seconds

## Step1: Identify the given variables### The problem provides the change in velocity, , and the average acceleration, (assuming standard gravitational acceleration).## Step2: Use the kinematic equation### The kinematic equation relating change in velocity, acceleration, and time is . We need to solve for .## Step3: Solve for time ### Rearrange the equation to solve for : . Substitute the given values: .## Step4: Calculate the time### Performing the division gives seconds.
