Ahas a mass of 7 kg, object b has a mass of 5 lbm, and object c has a mass of 0.5 slug. (a) which object has the largest mass? which object has the smallest mass? (b) find the weights of objects a, b and c (in both n and lbf) on the surface of mars.

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

3) Mass of object C = 0.5 slug

We know that 1 slug equals 14.594 kilograms Hence 0.5 slug equals

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

Now on Mars value of g equals

Thus the corresponding weights are as under:
