Review. As shown in Figure P10.77, two blocks are connected by a string of negligible mass passing over a pulley of radius r= 0.250 m and moment of inertia I. The block on the frictionless incline is moving with a constant acceleration of magnitude a = 2.00 m/s2. From this information, we wish to find the moment of inertia of the pulley. (a) What analysis model is appropriate for the blocks? (b) What analysis model is appropriate

As shown in Figure two blocks are connected by a string of negligible mass passing over a pulley of radius  and moment of inertia . The block on the frictionless incline is moving with a con­stant acceleration of magnitude .

From this information, we wish to find the moment of inertia of the pulley.

(a) What analysis model is appropriate for the blocks?

(b) What analysis model is appropriate for the pulley?

(c) From the analysis model in part (a), find the tension  ?

(d) Similarly, find the tension  ? 

(e) From the analysis model in part (b), find a symbolic expression for the moment of inertia of the pulley in terms of the tensions  and , the pulley radius r, and the acceleration a. 

(f) Find the numerical value of the moment of inertia of the pulley.

1. A block of mass m_1 = 2.00kgand a block of mass m_2 = 6.00 kg are connected by a masslessstirng over a pulley in the sape of a solid sik having radius R =0.250 m and mass M = 10.0 kg. These blocks are allowed to move on afixed block-wedge (what does this mean? T_1 and T_2 are equal?why?) of angle θ = 30 as in figure 6. The coefficient of kineticsfriction is 0.360 for both blocks. Draw free-body diagrams of bothblocks and of the pulley. Determine (a) the acceleration of the twoblocks and (b) the tensions in the string on both sides of thepulley.

2. Two blocks, as shown in figure 5, are connected by a stringof negligible mass passing over a pulley of radius 0.250 m andmoment of inertia I. The block on the frictionless incline ismoving up with a constant acceleration of 2.00 m/s^2. (a) DetermineT1 and T2, the tensions in the two parts of the string. (b) Findthe moment of inertia of the pulley. "Step by step please".
