You place a book of mass 5.00 kg against a vertical wall. You apply a constant force to the book, where the force is at an angle above the horizontal.

What is the vertical component of the force?

A. 5.00 sin(θ) N
B. 5.00 cos(θ) N
C. 5.00 tan(θ) N
D. 5.00 N

(Note: Please show work on a paper describing each step!)

Explanation on calculating work done on a cart at an angle above the horizontal and comparing it to work done horizontally . is 5 . The correct option is D .

Explanation:

Work Done on a Cart:

To calculate the work done on the cart by the boy when pulling at an angle of 30° above the horizontal:

Calculate the component of the force parallel to the direction of motion.
Find the work done using the formula: Work = Force × Distance.

Comparing Different Scenarios:

If the boy pulled horizontally instead of at an angle, the work done can be calculated similarly with the force being fully parallel to the motion direction.
