1. The problem statement, all variables and given/known data A 6.00 kg mass is pulled upwards by a massless string. It is being accelerated upwards at a rate of 0.500 m/s^2. Find the tension in the string. 3. The attempt at a solution I learned that tension is equal to weight, so I assumed T must = 60.0 N. But the answer key says different, so now I'm lost.
