I have these two equations that I'm supposed to set equal to each other and find the answer for h which is height for this problem. But I don't think I'm solving it correctly. 0 - (h/5) = -1.1(v0) - (1/2)(-9.8)(1.1)^2 (v0)^2 = 2(-9.8)(h/5 - h) My final answer was h...

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.50 m/s^2. When it is 255 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected...
