**1. 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?

**2. 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.

**3. 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
