15. An astronaut on the moon has a 110 kg crate and a 230 kg crate. How do the forces required to liftyihe crates straight up on the moon compare with the forces required to lift them on Earth?

The forces required to lift the crates straight up on the Moon is lesser than the forces required to lift them on Earth.

Given the following data:

Scientific data:

Mathematically, the weight of an object is given by the formula;

Where;

Weight A = 176 Newton.

Weight B = 368 Newton.

Weight A = 1,078 Newton.

Weight B = 2,254 Newton.

In conclusion, the forces required to lift the crates straight up on the Moon is lesser than the forces required to lift them on Earth.

Explanation:

Mass of carte 1 is 110 kg and that of crate 2 is 230 kg

Force required to lift crates is equal to its crate i.e. W = mg

On Moon, a = 1.625 m/s²

Weight of crate 1, W = 110 kg × 1.625 m/s²  = 178.75 N

Weight of crate 2, W = 230 kg × 1.625 m/s²  = 373.75 N

On Earth, g = 9.8 m/s²

Weight of crate 1, W = 110 kg × 9.8 m/s²  = 1078 N

Weight of crate 2, W = 230 kg × 9.8 m/s²  = 2254 N

Hence, this is the required solution.
