Problem 20E

An astronaut’s pack weighs 17.5 N when she is on the earth but only 3.24 N when she is at the surface of a moon. (a) What is the acceleration due to gravity on this moon? (b) What is the mass of the pack on this moon?

Step-by-Step Solution:

Solution 20E The weight is defined as how much normal reaction an object gets. An object of mass “m” is placed on the horizontal surface of earth exerts a force f mg on earth’s surface. By the same time, according to Newton’s 3rd law, it gets the same normal reaction force mg from earth’s surface. 2 So the weight will be mg = mass × 9.8 m/s . Step 1: The astronaut’s...
