Question

there are five questions for this scenario. a person is pushing a 75 kg bookshelf across a floor in a room on earth. the room is filled with air. the bookshelf is moving at a constant velocity of 4 m/s to the left. (e) assume that the bookshelf is transported to the planet mars, where g = 3.75 m/s². what is the mass of the bookshelf on mars?

Explanation:

Step1: Recall the concept of mass

Mass is an intrinsic property of matter and does not change with location (unlike weight, which depends on gravity). So the mass of the bookshelf on Mars will be the same as its mass on Earth.

Step2: Identify the mass on Earth

The mass of the bookshelf on Earth is given as 75 kg. Since mass is invariant, its mass on Mars will also be 75 kg.

Answer:

75 kg
