Catch the Ball

A ball is thrown straight up in the air at an initial speed of 30 m/s. At the same time the ball is thrown, a person standing 70 m away begins to run toward the spot where the ball will land.

How fast will the person have to run to catch the ball just before it hits the ground?

vperson = m/s
