Velocity, Force, and Acceleration

(1) Evil Kneivel rides his motorcycle off the rim of the Snake River Canyon at a horizontal velocity of 52 meters per second. How far away from the edge will he have traveled in 0.29 seconds? NOTE: Assume he does not hit bottom.
(2) Evil Kneivel rides his motorcycle off the rim of the Snake River Canyon at a horizontal velocity of 54 meters per second. How far has he dropped (meters) into the canyon in 1.48 seconds? NOTE: assume he does not hit bottom.
(3) If you throw a 44 kg rock off of a cliff, how fast does it accelerate to the ground? The earth exerts a force of 200 Newtons on the rock. (Newton = kg over meter per second^2)
(4) A book slides off a table top with a speed of 15 meters per second. It strikes the floor in 0.56 seconds. How tall was the table (in meters)?

Thanks for letting me work on your post. Here is my explanation:

1. horizontal traveling distance: Sx=52*0.29=15.08 m
Vertical traveling distance: Sy=1/2*9.8*0.29^2=0.41 m
The total ...
