Homework Statement
M1 and M2 are two masses connected as shown.
(M1 on hypotenuse of triangle, M2 on right side, (adjacent to right angle)) (Pulley at corner of them, Angle Theta is on the opposite corner)
The pulley is light and frictionless. Find the mass M1, given that M2 (4.50 kg) is moving downwards and accelerates downwards at 3.09 m/s2, that θ is 20.0°, and that μk is 0.450.
Homework Equations
The total force (which is the total mass times the acceleration) is equal to the sum of the forces. The normal force is NOT simply "m1g"--WHY?
