How to solve for initial velocity given acceleration and distance?

There is a deceleration of 16t ft/s^2 and the final distance traveled is 200 ft. before coming to a stop. I know the relations between position, velocity, and acceleration when using calculus, but I can't figure out how to solve for the time t in the distance equation, and am a little unsure of how to get the... show more There is a deceleration of 16t ft/s^2 and the final distance traveled is 200 ft. before coming to a stop.

Any help at all would be greatly appreciated!!
