84. We use W p = mg p , where W p is the weight of an object of mass m on the surface of a certain planet p , and g p is the acceleration of gravity on that planet. (a) The weight of the space ranger on Earth is W e = mg e = (75 kg) (9.8 m/s 2 ) = 7.4 × 10 2 N. (b) The weight of the space ranger on Mars is

Unformatted text preview: W m = mg m = (75 kg) (3.7 m/s 2 ) = 2.8 × 10 2 N. (c) The weight of the space ranger in interplanetary space is zero, where the effects of gravity are negligible. (d) The mass of the space ranger remains the same, m =75 kg, at all the locations....
