During World War I, mortars were fired from trenches 3 feet down. The mortars had a velocity of 150 ft/s. Determine how long it will take for the mortar shell to strike its target. (note:-16x^2 + bx + y-intercept,
where the 't' represents the velocity per second)

I just need to know how to set it up
