[SOLVED] Resultant force on a car Homework Statement A 1070 kg car is pulling a 320 kg trailer. Together the car and trailer move forward with an acceleration of 2.01 m/s2. Ignore any frictional force of air drag on the car and all frictional forces on the trailer. Determine the following. (a)...

Homework Statement A 33 N force acts on an object at 30 degrees West of South while a 17 N force acts on the same object at 30 degrees North of West. What is the resultant force and direction. Force1= 33 N Force 2= 17 N Homework Equations Force diagram? Cos? The Attempt at a...

adding vectors and getting their resultants are Quite easy but understanding the problem is not.. in my problem it says that three of the forces are 100N, 60 degrees above the x axis; 200N, 140 degrees above the x-axis and 250N, 320 degrees above the x axis..The resultant is 100N along the...

Homework Statement So I am using Law of sine/cosines to find resultant force R and its direction. My teacher gave me a hint to decompose the 600 and 800 into x and y components...but I have done this and cannot see what it helps me to derive? Anyone else see it? Casey Also, I have drawn...

Homework Statement Okay, I am only allowed to use law of cosines and sones to find the resultant force F_r I am having a hell of a time finding a usable angle after drawing my parellelogram..so obviously I am in need of sleep. What am I missing here? (pic is clickable) Casey

Please HELP! I need help with a question...I don't know how to do it...can someone please tell me how. This question is about calculating the resultant force using vectors. Question: There is a parachutist with a 500 N force acting upwards on him and a 1000 N force acting downwards on him...

What type of equation would I use to find the resultant force? Do I just add the vectors together? Or change them to X and Y variable?

[SOLVED] Average Resultant Force Hi for this question http://tinyurl.com/3cbxlq What I try is Average Force =(mv-mu)/t =2000(6-4)/4 =1000 but this is not one of the answers. Meaning it is wrong. May I know how to do this question?

two ropes are attatched to a heavy object. the ropes are given to two strong people with instructions for each to pull with 1000N of force. what is the total resultant force if the two women pull.. in the same direction_________F=2000N in opposite direction__________F=0N at right angles...

I can't seem to figure this problem out... Three forces in the x-y plane act on a 3.70 kg mass: 14.50 N directed at 478.0°, 11.00 N directed at 117.0°, and 10.70 N directed at 222.0°. All angles are measured from the positive x-axis, with positive angles in the counter-clockwise direction...
