1352 pound
Step-by-step explanation:
Kindly find attached for your reference
This problem bothers on the topic of work energy and power
Given data
Applied force = 3200 pounds
Angle of application = 25°
We know that the horizontal force =
F= 3200cos 25°
Hence the vertical component of this force = F= 3200sin 25
=3200*0.42261
= 1352.352
to the nearest pound
F = 1352pound

<h2>30.67 pounds of 32% copper alloy and 10.33 pounds of 65% copper alloy</h2>Step-by-step explanation:
First alloy contains 32% copper and the second alloy contains 65% alloy.
We wish to make 44 pounds of a third alloy containing 42% copper.
Let the weight of first alloy used be in pounds and the weight of second alloy used be
in pounds.
Total weight =
Total weight of copper =
Subtracting 32 times first equation from second equation,
∴ 30.67 pounds of first alloy and 13.33 pounds of second alloy were used.
