Wt. = 80kg * 1.625N/kg = 130.7 N.
g on moon = 1.625 m/s^2.
g on moon = 1.625 m/s^2.
Weight = Mass × Acceleration due to gravity
The acceleration due to gravity on the surface of the moon is approximately 1/6th of that on Earth, which is about 1.622 m/s².
Weight = 80.0 kg × 1.622 m/s²
Weight ≈ 129.76 N
Therefore, the weight of a man with a mass of 80.0 kg on the surface of the moon is approximately 129.76 N.
The mass of the man is given as 80.0 kg (kilograms), and the weight on the surface of the moon is given as 156 N (Newtons).
The gravitational acceleration on the moon is approximately 1/6th (0.166) of the gravitational acceleration on Earth, which is 9.8 m/s².
So, we can calculate the weight of the man on the moon as follows:
weight on the moon = mass × gravitational acceleration on the moon
weight on the moon = 80.0 kg × 0.166 × 9.8 m/s²
weight on the moon = 80.0 kg × 1.6136 m/s²
weight on the moon ≈ 129.088 N
Therefore, the weight of the man with a mass of 80.0 kg on the surface of the moon is approximately 129.088 N.
