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.
Momentum = mass * velocity
(aka p=mv)
p=0.145*40
p= 5.80 kg m/s

Answer:
1. 75N
2. 67,983 J (=67.98 kJ)
Explanation:
1. Work = Force x Distance
we are given that Work = 1,500J and Distance = 20m
hence,
Work = Force x Distance
1,500 = Force x 20
Force = 1,500 ÷ 20 = 75N
2. Potential Energy, PE = mass x gravity x change in height
we are given that mass = 165 kg and change in height = 42m
assuming that gravity, g = 9.81 m/s²
Potential Energy, PE = mass x gravity x change in height
Potential Energy, PE = 165 x 9.81 x 42 = 67,983 J (=67.98 kJ)
