Your neighbor's pesky kid insists on shooting 25.0 {rm g} rocks at your new 2.25 {rm kg} light fixture hanging by a 26.0 {rm cm} wire from the ceiling of your porch.

If each rock strikes the fixture traveling at 10.0 {rm m}/{rm s} horizontally and rebounds at 2.00 {rm m}/{rm s} backwards, how high above the lowest point does the impact make your light fixture swing?
