Question

A 34.5-kg box is suspended by a 24.6-newton rope, as shown.What is the tension at the top of the rope?(a) 59.1 N(b) 124 N(0) 314 N(d) 363 N

Answer 1

The tension at the top of the rope is equal to the sum of the weight of the box and the rope, then we have:

$(34.5)(9.81)+24.6=363.04$

In this we multiply the acceleration of gravity by the mass of the bos to get its weight. Therefore the answer is d.
