[SOLVED] 2 more basic problems
3 dogs are pulling a sled with a combined weight of 145 kg the dogs are pulling
1) pulling at a force of 83N at 15.5(degrees) left of forward
2) pulling at a force of 75N at 9 (degrees) right of forward
3) pulling at a force of 77N at 12(degrees) right of forward
sled is moving a a constant velocity find the coefficient of kinetic friction between the sled and snow,
so the sled has a force of 1422.45N in the opposite direction the dogs are pulling, so then i have to find the vertical forces the dogs exert and add them together? so to find vertical i use f.sin(theta) then add the 3 together so i know.
1) Fy=22.18N
2) Fy=11.73N
3) Fy=16N
i don't even know if I am going about this the right way,
ill give problem 2 once i solve this
