# I think my physics teacher doesnt have a clue

## Homework Statement

we did a experiment in class shooting marbles and taking measurements. The size of the Marble is .0019 meters and with a photo gate timed it at .0037 secs. Giving me a initial speed of .5135 m/s2. I am now trying to find time. with the angle being 70 degrees

## Homework Equations

She gave us this equation to find time T= Velocity*Sin(angle)/Gravity.

## The Attempt at a Solution

I have tried several times looking at the units. We did the experiment and the distance it traveld was roughly 1.62 meters. KNowing this i figured the time to be roughly 3.15s. But using the formula she gave me i cant come up with the same answer what am i doing wrong?
