A body whose weight is 784 N on the earth's surface will have a weight of N when transported to a planet whose acceleration due to gravity is g = 22.5 m/s2. Take the acceleration due to gravity on earth to be 9.80 m/s2.

Explanation:

Weight = Mass x Acceleration due to gravity

In Earth

         784 = Mass x 9.81

         Mass = 79.92 kg

         Mass of body = 79.92 kg

Mass is a constant, it will not change planet to planet.

In planet

         Weight = Mass x Acceleration due to gravity

         Weight = 79.92 x 22.5

         Weight = 1798.17 N

Weight of body in planet is 1798.17 N

i hope that ! =)

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
