Abdul of mass 50 kg is standing in an elevator of his building. The elevator is moving upwards and is slowing down at a rate of 2.0 m/s? What is Abdul's apparent weight?
Use g = 10 m/s

Abdul has an apparent weight of 600 newtons.

Explanation:

The statement is incorrectly written. Its correct form is:

Abdul of mass 50 kg is standing in an elevator of his building. The elevator is moving upwards and is slowing down at a rate of 2.0 m/s2. What is Abdul's apparent weight? Use g = 10 m/s2.

According to the statement, we know that elevator and Abdul himself are moving upwards and decelerating, which means that Abdul feels a force from elevator is the same direction of his weight. From 2nd Newton's Law we find the following equation of equilibrium:

(1)

Where:

- Apparent weight, measured in newtons.

- Mass of Abdul, measured in kilograms.

- Gravitational acceleration, measured in meters per square second.

- Net acceleration of the elevator-Abdul system, measured in meters per square second.

In (1) we clear the apparent weight:

If we know that , and , we find that the apparent weight of Abdul is:

Abdul has an apparent weight of 600 newtons.

this means that the temperature of both substances will be equal

i think if it were me i whould divide 300 dide 15
