single cable attached to the 10 kg mass?
Tension is the only force pulling up. Fnet down is gravity, or mg. Mg = 98 N in this case. Now, apply Newton's 2nd law. F=ma F= 10 * 2 F = 20 So the total force is 20 upward. That means that the tension applies enough to balance out the force of gravity and accelerate the object. So basically, 98 + 20. This equals 118. So your answer would be 118 Newtons. The distance is just meant to throw you off.
