The bullet remains in the block, and after impact the block lands d = 1.76 m from the bottom of the table. Calculate the initial speed of the bullet.

1.13=4.9t^2 solve for t, then use that t to find the initial horizontal velocity of the block/bullet

1.76=v'*t solve for v'

then conservation of momentum...

(m1+m2)v'=m1*v

solve for v.
