What do I do to get the net force

AI Thread Summary
To find the net work done on the mincemeat pie sliding down the ramp, first calculate the gravitational force acting on it and the force of friction using the coefficient of kinetic friction. A free body diagram can help visualize the forces, including the component of gravitational force parallel to the ramp and the frictional force opposing the motion. The net force is the difference between the gravitational force down the ramp and the frictional force. The net work done can then be calculated by multiplying the net force by the displacement of 18 meters. The initial calculation of 327.23 J may need verification against these steps.

This is the question I am given:

The largest mincemeat pie ever created had a mass of 1.020 x 10³ kg. Suppose that a pie with this mass slides down a ramp that is 18.0m long and is inclined to the ground by 10.0°. If the coefficient of kinetic friction is 0.13, what is the net work done on the pie during its decent.

Ok, we just started this unit. So I know the equation for work. the displacement is 18m and the angle is 10.0°. What do I do to get the net force and how do I make the coefficient come into this problem.

since you are on to work then you know how to sum forces correct? Draw out the free body diagram, sum forces, once you have the forces summed I think you know where to go with it. If not let me know.
 
no i don't think I am gettin it. can u give a few more clues. thx
 
ok I am gettin 327.23 J but i highly doubt it's right

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
