## Homework Statement

A burst of compressed air pushes a pellet out of a blowpipe. The force exerted by the air on the pellet is given by F(t)=F0e(−t/τ), where τ is called a

*time constant*because it has units of time.

What does F0 represent?

## Homework Equations

F0 represents the maximum force.

F0 represents the minimum force.

F0 represents the average force.

F0 represents the force at time t = 0.

## The Attempt at a Solution

i can check as many that apply, i originally though it was the force at t=0 because that would mean it's the inital values. that wasn't right. can someone help
