Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with massm1 17.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is=a = 1.80 m/s², and the tension in the segment of string attached to this block is T₁. The hanging block has a mass of=m2 23.5 kg, and the tension in the string attached to it is T2. The radius of the pulley is r = 0.350 m and its moment ofinertia is I.
