Final answer:
To calculate the total force required for lifting a box vertically, consider the weight of the box and the force applied by the person. Add these two forces together, making sure the directions are opposite.
Step-by-step explanation:
In order to calculate the total force required for lifting a box vertically, you need to consider two main forces:
- The weight of the box: This force is equal to the product of the mass of the box and the acceleration due to gravity. It acts vertically downwards.
- The force applied by the person: This force is exerted in the opposite direction to the weight of the box and is necessary to lift the box.
The total force required can be calculated by adding the weight of the box and the force applied by the person. It is important to note that the direction of the force applied by the person should be opposite to the direction of the weight of the box.
