an object hose mass is 200 kg moves at a velocity of 50m/sec and altitude of 200m,both measuredc relative to the surface of the earth. the acceleration of gravity can be taken as constant at g=9.8 m/sq.sec.
(a) if the kinetic energy increased by 2400KJ with no change in elevation,what would be the final velocity in m/s
(b) if the potential energy increased by 2400KJ with no change in velocity,what would be the final elevation in m
