Answer:
Explanation:
If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.
Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.

John spent $3500.
140% of $3500 is $4900.
So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.
However, the question asks for the price of a single pine. To find the unit price of a single pine, divide the total revenue by 15.

The angle turned is obtained as 3.77 rads.
<h3>What is the angle of rotation?</h3>
We have the following information about the disk;
velocity 1= 7200 RPM
velocity 2 = 0 RPM
time taken = 0.01 seconds
We must convert from RPM to rad/s using the relation;
2π·7200/60 = 754 rad/s
Using;
θ = ωavt
θ = (754 rad/s + 0 rad/s)/2 * 0.01 seconds
θ = 3.77 rads
