Catch the Ball

A ball is thrown from the ground level straight up in the air at an initial speed of v0 = 30 m/s. A person standing d = 70 m away begins to run at a constant speed toward the spot where the ball will land at the same time the ball is thrown.

How fast will the person have to run to catch the ball at the ground level just before it would have hit the ground?

vperson = m/s
