free fall?

A crane, moving at the steady velocity of 5 m/s, is lifting a load of bricks when one brick falls off 6 m above the groundDescribe the motion of the free brick by sketching x vst with the ground as the reference point(a) What is the greatest height the brick reaches? (b) How long does it take to reach the ground? (c) What is its speed just before it hits the ground?-so confused by this stuff.
