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.

(1) assume that the bookshelf is transported to the planet mars, where g = 3.75 m/s². what is the weight of the bookshelf on mars? show your calculation.

Explanation:

Step1: Recall the weight formula

The formula for weight is \( W = m \times g \), where \( W \) is weight, \( m \) is mass, and \( g \) is the acceleration due to gravity.

Step2: Identify given values

The mass of the bookshelf \( m = 75 \, \text{kg} \), and the acceleration due to gravity on Mars \( g = 3.75 \, \text{m/s}^2 \).

Step3: Calculate the weight

Substitute the values into the formula: \( W = 75 \, \text{kg} \times 3.75 \, \text{m/s}^2 \).

$$ W = 75 \times 3.75 = 281.25 \, \text{N} $$

Answer:

The weight of the bookshelf on Mars is \( 281.25 \, \text{Newtons} \).
