A ball of mass m, and a block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the Figure 1.1. The block lies on a frictionless incline of angle 0. a. Find the magnitude of the acceleration of the two objects and the tension in the cord. b. What happens in this situation if the angle 0 = 90? c. What happens if the mass m= 0? %3D %3D a m2 m1 Figure 1.1 Illustration taken from Physics for Scientists and Engineers 6th Edition by Serway & Jewett
