The problem mentions nothing about air resistance so we can assume that our forces our conservative. This meas that the sum of your forces at position 1 (her highest point) is equal to the sum of the forces at position 2 (her lowest point).
KE1 + PE1 = KE2 + PE2
You can elimitate your KE1...
Ok, that gave me the correct answer, but i would like to be sure that I have a firm grasp on this before i quit monitoring this thread.
I am still confused why you don't include the weight in your net force. Is it because your thrust force is at an angle and you are only using the horizontal...
Yes I broke the thrust force down into x and y components. The y component was the equivalent of the normal force and thus equal to the weight. This is how I answered the first half of the problem. I also have the x component of the force, but not the force that opposes this or the acceleration...
Calculating the vertical forces wasn't a problem because the acceleration in that direction was understood to be 0 thus making it an equilibrium problem. I am stuck on the horizontal forces because I have 2 unknowns and I cannot find a way to figure either of them out.
I know that my [net...
Homework Statement
On takeoff, the combined action of the air around the engines and wings of an airplane exerts a 7049N force on the plane directed upward at an angle of 58.7 above the horizontal. The plane rises with a constant velocity in the vertical direction while continuing to...
