Extracted text: Consider the following specific case of the system described in the example above. Suppose the angle 0 is 75.0° and the mass of the ball is 6.90 kg. (a) Determine the mass of the block if the tension in the cord is equal to the weight of the ball: T = m,g. kg (b) What is the acceleration in this case? m/s?


Extracted text: Suppose that in the same Atwood setup another string is attached to the bottom of m, and a constant force f is applied, retarding the upward motion of m,. If m, = 5.80 kg and m, = 10.00 kg, what value of f will reduce the acceleration of the system by 42%?
