1. The problem statement, all variables and given/known data Find the acceleration of an elevator going upwards and downwards if your initial mass is 45 kg, when its going downwards is 36 kg, and when its going upwards is 47 kg. 2. Relevant equations F=ma 3. The attempt at a solution W=45(9.8) W=441 N W=47(9.8) W=460.6 N T=m(a+9.8) 460.6=45(a+9.8) 460.6=45a+441 19.6=45a 0.436 m/s^2= upward acceleration Is this right???
