In summary, pulling a box vertically involves applying a force in an upward or downward direction to move the box in a straight line. This is typically done by grasping the box with your hands and using your arms and upper body muscles. The purpose of pulling a box vertically is to transport or reposition it, but it can also put strain on muscles and joints if not done properly. Tools such as pulleys, hoists, and dollies can assist with this task and reduce the risk of injury.

Homework Statement


A box of mass 5.0 kg is pulled vertically upwards by a force of 68 N applied to a rope attached to the box. Find a) the acceleration of the box and b) the vertical velocity of the box after 2 seconds.

Homework Equations


ma = Force and a = T/m -g
a = 68/5 - 9.8 = 3.8 m/s^2

v = vo + axt
v = 0 + 3.8 x 2 = 7.6 m/s.

Does this look right?

Thanks!

1. What is the definition of pulling a box vertically?

Pulling a box vertically refers to the action of applying a force in an upward or downward direction to move a box in a straight line.

2. How do you pull a box vertically?

To pull a box vertically, you would typically grasp the box with your hands and use your arms and upper body muscles to apply an upward or downward force.

3. What is the purpose of pulling a box vertically?

The purpose of pulling a box vertically is to move the box in a specific direction, either upward or downward, in order to transport or reposition it.

4. What are the potential risks of pulling a box vertically?

Pulling a box vertically can put strain on your muscles and joints, especially if the box is heavy. It is important to use proper lifting techniques and to avoid overexertion to prevent injury.

5. Are there any tools or equipment that can assist with pulling a box vertically?

Yes, there are tools such as pulleys, hoists, and dollies that can assist with pulling a box vertically. These tools help to reduce the amount of force needed and can also provide better control and stability while moving the box.
