two horizontal wire which are separated by 50 degrees are pulling on a 2180 kg mass and cause it to accelerate to the west at 0.25 m/s2. the tension in each rope is 4200.
a) find the net force on the mass
b) how much friction is acting on the mass?
2. Relevant equations
f = fah-fnet
3. The attempt at a solution
so i drew out a free body diagram and calculated the components.
x1 = cos25 (4200) = 3806 N
y1 = sin25 (4200) = 1775 N
x2 = the same as x1
y2 = the same as y1
i found fnet by going mass * acceleration and got 545 N
now calculating friction is difficult. i do not know if i am supposed to use only one x component or both. am i supposed to add 545 or subtract it? all help is appreciated. thanks
