what do you know about an object in freefall? what equation governs its trajectory? in this case it's a single dimensional trajectory. think of the acceleration due to gravity.

Use the equation \[x_f=x_o+v_ot+{1 \over 2}at^2\] Xf is final position Xo initial position Vo initial velocity a acceleration (in this case just gravity) t time For your problem you can set Xo=0, Vo=0. plug in the rest and you'll know how far the object has fallen after time of 1.1 sec. I know this equation is not really needed because the values get set to 0 so here's the shorter version people tend to remember more: \[h={1 \over 2}at^2\]Now you know for reference where this equation is from.

For question (b) take the first equation I gave you and rearrange for Vo. plug in the values and you should get the answer.
