2, The figure below shows acord attached toacart that can slide along africtionless horizontal raill aligned along an x axis. “The left end of the cord is pulled over a pulley, of negliglible mass and friction and at cord helighth =1.20 m, so the cart Slides from X1 三 3.00 m to x2 = 1.00 m.” During the move, the tension in the cord is a constant 25.0 N. What is the change in the kinetic energy of the cart during the move》 ITIensions Ti and T? are equal in magnitude here, but try both ways to solve the problem: (90. Ti pulls the cord and the cart together.(b). T2 pulls the cart only. Both ways should lead to the same answer.
