The terminal speed of a penny is 11 m/s. By neglecting air resistance, calculate how long it takes for a penny falling from rest to reach half of this speed

**2. Homework Equations**

I thought maybe you had to use one of the kinematic equations but that didnt work

**3. The Attempt at a Solution**

I tried Vf-Vi/a = delta T

Also, I tried dividing 11 m/s by gravity and that didnt work.

Im not sure if I am totally missing an equation needed or if I am making this way harder than it really is. Any help would be greatly appreciated!
