Answer:
1) Object C has the largest mass.
2)Object has the smallest mass.
3) Weight of A = 26.6 Newtons
4)Weight of B = 8.6184 Newtons
5)Weight of C = 27.7286 Newtons
Explanation:
Since all the given masses have different unit's we shall convert them all into a same base unit for comparison. The base unit is selected to be kilogram.
Hence
1) Mass of object A = 7 kilogram
2) Mass of object B = 5 pounds
We know that 1 pound equals 0.4536 kilograms Hence 5 pounds equals
[tex]0.4536\times 5=2.268kg[/tex]
3) Mass of object C = 0.5 slug
We know that 1 slug equals 14.594 kilograms Hence 0.5 slug equals
[tex]14.594\times 0.5=7.297kg[/tex]
Upon comparing all the 3 masses we conclude that object C has the largest mass and object B has the smallest mass.
Part b)
Weight of an object is given by
[tex]Weight=mass\times g[/tex]
Now on Mars value of g equals [tex]3.8m/s^{2}[/tex]
Thus the corresponding weights are as under:
[tex]W_{A}=3.8\times 7=26.6N\\\\W_{B}=3.8\times 2.268=8.6184N\\\\W_{C}=3.8\times 7.297=27.7286N\\\\[/tex]
