Gravity

This “planet” has a gravity field higher than Jupiter. His whole body will “feel” nearly three times heaver. Unless this man was built like Arnold Schwarzenegger, he probably wouldn’t be able to lift his head without breaking his neck.

Uh.....62 kg ??

Umm I don't know about that one Chris 

62Kg is a mass not a weight.   (corrected)

1Kg=9.8N     ON EARTH

62Kg=607.6N    ON EARTH

Technically Jack can lift a maximum weight of   607.6N    (It would be the same on the alien planet)

That sounds right to me anyway

If Jack can lift a mass of 62kg on Earth, then he is lifting a weight of 62*9.8 N (= 607.6N).

Gravitational acceleration on the alien planet is 9.8*62/22 m/s² (= 27.6 m/s²)

.

Careless error on my part I  shall fix it (I did mean 62 not 22)

Good point 7up - i didn't think of that.   LOL
