Find the rate at which the system will accelerate, and calculate how far each mass should move in 3.2 s, if the system is initially moving at 2.0 m/s. Assume that the pulleys are frictionless, that the coefficient of friction between the ramp surface and the 250 g mass is 0.08, and that the ramp is inclined at an angle of 25° above the horizontal.

how did you get the two other masses?
