A 15.0-kg test rocket is fired vertically from Cape Canaveral. Its fuel gives it a kinetic energy of 1961 J by the time the rocket motor burns all the fuel. What additional height will the rocket rise?
m
- how do you organize this?
how do the J's fit in?

  • physics -

    KE =PE = m•g•h
    h = KE/m•g =1961/15•9.8 =13.34 m
