A50 kg box hangs from a rope. what is the tension in the rope if the box moves up at a steady 5.0 m/s

There are two forces acting on the box: the tension of the rope (upward) and the weight (downward). The problem says the box moves up at constant speed: this means that its acceleration is zero, therefore for Newton's second law, the resultant of the forces acting on the box is zero. This implies that the tension of the rope is equal to the weight of the box, which is:

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
