A 10.0 -kg test rocket is fired vertically from Cape Canaveral. Its fuel gives it a kinetic energy of $1960 \mathrm{J}$ by the time the rocket engine burns all of the fuel. What additional height will the rocket rise?

A rocket is fired vertically starting from rest. Neglecting air resistance, what velocity will it attain in 68 s if its initial mass is 13 000 kg and fuel is burnt at the rate of 124 kg s−1, the gases being ejected at a velocity of 1950 m s−1 relative to the rocket? If the fuel is exhausted after 68 s what is the maximum height that the rocket will reach? Take g = 9.8 m s−2.
