Question

A water balloon was dropped from a high window and stroke his target 1.1 seconds later, if the balloon left the persons hand -5.5 85 m/sec, what was it’s velocity on impact?

Answer 1

I suspect typos.

If the balloon was dropped, its initial velocity was 0 m/s, not
-5 or -5.85 m/s

Not sure what that " 85" is doing there.

But recall that v(t) = v₀ - 9.81t
