2) Desde un globo aerostático, que está a una altura de 3710 m y subiendo con una velocidad ascendente de 36 m/s, se suelta un paquete de medicinas de 80 kg. Calcula:
a) La energia mecánica del paquete cuando llega al suelo.
b) La altura que haya descendido cuando alcanza una velocidad de 100 m/s.
c) La velocidad a la que el paquete llega al suelo.

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is
