A cord passing over a pulley connects two masses, as shown, where m1 = 2.80 kg and m2 = 6.50 kg. Assume the pulley and surfaces are frictionless, and the cord is massless and does not stretch. (Due to the nature of this problem, do not use rounded intermediate values-including answers submitted in WebAssign-in your calculations.) (4) (a) What is the acceleration of each block? (Enter the magnitude in m/s2.) m/s2 (b) What is the tension in the cord (in N )? N
