Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with mass m,- 18.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is
a-180 m/s, and the tension in the segment of string attached to this block is T. The hanging block has a mass of m, - 25.5 kg, and the tension in the string attached to it is T. The radius of the pulley is r0.330 m and its
moment of inertia is I. The incline plane makes an angle of - 37.0* with the horizontal,
(a) What is the tension force T,? (Give your answer, in N, to at least three significant figures.)
