Please answer ALL of the questions:

For the system below, mi 19 kg, m2 26 kg and m pulley 15 kg, if the coefficient of friction between crate 1 and the table is u 0.13 what is the acceleration? m/s Pulley my Need Help? Read it Chat About t -1 points My Notes GioCP2 8.P.0 A board of length 2.7 m is attached to a floor with a hinge at one end as shown in the figure below. The board is initially at rest and makes a angle of 50o with the floor. If the board is then released, what is its angular acceleration? rad/s Hinge

Explanation / Answer

Net force = Total mass * acceleration = (19+26) * a=45*a

The weight of m2 is causing the two blocks to accelerate. W = 26 * 9.8 = 254.8
The friction force is causing the two blocks to decelerate. Ff = 0.13 * 19 * 9.8 = 24.206

Net force = 254.8
