1. The problem statement, all variables and given/known data A 5.0-kg mass hangs at the end of a cord. Find the tensionin the cord if the acceleration of the mass is a)1.5 m/s squared up, b) 1.5 m/s squared down Answers: a) 57 N; b)42 N ____________________________________________________________________ A sample question in our physics book is "An object of mass m is supported by a cord. Find the tension in the cord if the object is a) at rest, b) moving at a constant velocity, c) accelerating upward with acceleration a = 3g/2, and d) accelerating downward at a = 0.75g a) ay = 0: FT - mg = may = 0 or FT = mg b) ay = 0: FT - mg = may = 0 or FT = mg c) ay = 3g/2: FT - mg = m(3g/2) or FT = 2.5mg d) ay = -3g/4: FT - mg = m(-3g/2)or FT = 0.25mg 2. Relevant equations The relevant equations are: See 1 3. The attempt at a solution I know there is something I'm just not getting in this problem... It should be so simple but everytime i look at it and attempt it i just keep getting the wrong answer... Also in the sample problem, how are they getting 2.5 out of 3g/2??? It's just not clicking!!!
