Question

. A rocket has a mass of 4.29*106 kg on earth. What is its mass in SI units? What is its weight in SI units? If the rocket is on the moon, where acceleration due to gravity is g = 1.61 m/s2 , determine its mass and its weight on the moon in SI units.

Answer 1

(a)

A rocket has a mass of $m_1=4290000kg$ on Earth.

(b)

A rocket has a weight of $P_1=4290000kg(9.81m/s^2)=42084900N$ on Earth.

(c)

A rocket has a mass of $m_2=4290000kg$ on the Moon.

(d)

A rocket has a weight of $P_1=4290000kg(1.61m/s^2)=6906900N$ on the Moon.
