... 7. The gravitational attractive force on the moon is 1/6 that of earth giving objects an acceleration of 1.67 m/s2 (in other words, on the moon g= 1.67 m/s2). What would be the mass of a 150-kg TV set on the moon? 150 kg 8. Using the concept of combining vectors, determine the net force when a 6 N a ...
