Ok! I made a coordination where x-axis goes through this inclination.
Sigma Fx = max = 0 because ax = 0
Fx = N + W + "Pull"
Fx = 0 + mgsin21 + "Pull" = 0
Pull = -15452 N
am I right?
A farm tractor tows a 4400-kg trailer up a 21 degree incline at a steady speed of 3.0 m/s. What force does the tractor exert on the trailer? (Ignore friction.)
How would you get the answer 15000 N.
