A 1.50 kg water balloon is shot straight up with an initialspeed of 5.00 m/s.
(a) What is the kinetic energy of the balloon just asit is launched?
J
(b) How much work does the weight of the balloon do on the balloonduring the balloon's full ascent?
J
(c) What is the change in the gravitational potential energy of theballoon Earth system during the full ascent?
J
(d) If the gravitational potential energy is taken to be zero atthe launch point, what is its value when the balloon reaches itsmaximum height?
J
(e) If, instead, the gravitational potential energy is taken to bezero at the maximum height, what is its value at the launchpoint?
J
(f) What is the maximum height of the balloon?
