A cylinder of unknown mass m is attached to a cord that is wrapped around a 3 kg pulley shaped as a hoop. The pulley-cylinder system is initially at rest. Once the cylinder is released, the linear acceleration of the pulley is 2m/s^2. Assume the axle of the pulley to be frictionless. The moment of inertia for a hoop is mr^2. Calculate the unknown mass of the cylinder m and calculate the force of tension

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the answer would be   dignified - apex

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

not moving. pos accel,
