Arocket has a mass 250 x (10^3) slugs on earth. specify(a) its mass in si units, and(b)its weight in si units. if the rocket is on the moon where the acceleration due to gravity is gm=5.30ft/s2, determine to three significant figures (c) its weight in si units, and (d) its mass in si units.

Explanation:

It is given that,

Mass of the rocket,

(a) The SI unit of mass is kilogram (kg). The relation between slugs and the kg is given by :

1 slug = 14.59 kg

So,

Mass of the rocket, m = 3647500 kg

(b) Weight of the rocket is given by :

W = m g

or

(c) If the rocket is placed on the moon. The acceleration due to gravity on the moon is,

Mass is the amount of matter contained inside the object. So, the mass of the rocket remains the same i.e. 3647500  kg

Weight of the rocket on the moon is,

W = 5872475 N

or

Hence, this is the required solution.
