**David**, Thursday, March 22, 2012 at 10:57pmBecause of the symmetry in the path of a projectile, it will return to your hand with a speed of 40 m/s downward. Its total displacement is 0 since it returns to starting position.

To find the distance traveled, multiply the height it reaches by 2. Find the height using kinematic equation:

V^2 = V0^2-2gy

where y = h and and V^2 =0 because velocity is 0 at the top of its path.
