T = [l]\frac{}{}[/f]

This is what I need!

The Attempt at a Solution

t=[75]\frac{}{}[/30] = 2.5


I was out for an entire week, and the teacher sent home a sheet full of questions like this. I don't have any of the equations though. Help please!?

The period is the time it takes a pendulum to complete one oscillation. If it makes 30 in 75 seconds how long will it take to do one?
