Question

An astronaut has 80 kg mass on earth What will be his mass and weight on mars where g=3.7 m/s2.​

Answer 1

Step-by-step explanation:

1.Mass of astronaut,m = 80 kg

Weight on earth = mg = (80)(9.8) N = 784 N

Weight on mars = mg' = (80)(3.7) N = 296 N

2.

Weight of the body, W = 30 N =mg

Mass of the body, m = W/g = 3.06 kg

New weight of the body, W' = mg' = (3.06)(3.5)N = 10.71 N

3. Mass remains the same but weight becomes zero.

Answer 2

Answer:

a) 784 N weight on the of the astronaut

b) 296 N on the mars
