Rope up force = 146 sin 50
Rope horizontal pull force = 146 cos 50
weight down = 350 Newtons (I assume you mean Newtons not mass in kg)
net normal force on floor = 350 - 146 sin 50
friction force back = mu ( 350- 146 sin 50)
friction force = pull force
mu ( 350 - 146 sin 50) = 146 cos 50
Rope horizontal pull force = 146 cos 50
weight down = 350 Newtons (I assume you mean Newtons not mass in kg)
net normal force on floor = 350 - 146 sin 50
friction force back = mu ( 350- 146 sin 50)

mu ( 350 - 146 sin 50) = 146 cos 50
