A fountain nozzle points vertically upwards. Water leaves the nozzle and rises 5.0 m above it before it stops rising. Air resistance is negligible. Use g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg.
At what speed does the water leave the nozzle?
7.1 m/s7.1\ \mathrm{m/s}7.1 m/s
5.0 m/s5.0\ \mathrm{m/s}5.0 m/s
14 m/s14\ \mathrm{m/s}14 m/s
10 m/s10\ \mathrm{m/s}10 m/s
