here's the question:
a mass of 100kg is pulled directly upward a distance of 5m by a rope with acceleration 1m/s^2. what is the work done by the tension force?
so the normal force is mg, 100kg*10m/s^2(gravitational constant given)= 1000N
the applied force is 100kg*1m/s^2= 100N
so is the tension 1000+100? if so the work done is 1100N*5m= 5500J
it's being pulled straight up, so the angle is 0, cos0=1
is it correct to add the two forces to find the total tension?
