A physics book slides off a horizontal tabletop with a speed of 1.10 m/s. It strikes the floor at 0.350 s. Ignore air resistance. Find (a) the height of the tabletop above the floor, (b) the horizontal distance from the edge of the table to the point where the book strikes the floor, and (c) the horizontal and vertical components of the book’s velocity, and the magnitude and direction of its velocity, just before the book reaches the floor.

I used this equation with no success...

1.10(.35)+1/2(-9.8)(.1225)

= .385 + (-.60025)

= -.215 m

where do i go from here? Thanks.
