On a mass of 100 kg, a force of 120 N acts right and at an angle of 30 degrees to the horizontal. If the coefficient of sliding friction is .1 what is the acceleration of the mass?
Net force= mass*acceleration
Horizontal force -frictionalforce = mass*acceleration
100N* cos30 -(100sin30+mg)(.1)= m*acceleration
check that.
When you write "mass*acceleration" do you mean the acceleration of the mass?
100N* cos30 -(100sin30+mg)(.1)= m*acceleration
15.425- [(-98.803 + (100)(-9.8)](.1)
15.425- (-1078.803)(.1)
and so I got 123.305 as the answer.
I also did the math in radians mode. Is this correct?
