Aboard, with a weight of 85 n and length of 6.0 m is supported by two vertical ropes. rope a is connected to one end of the board and rope b is connected a distance of 1.5 m from the other end of the board. a box with a weight of 25n is placed on the board with its center of mass 1.0 m from rope a. what is the tension in rope a?

47.78 N

Explanation:

Given

Weight of Board W=85 N

length of board L=6 m

Rope B is connected from the other end of the board at a distance of 1.5

Box with a weight of 25 N is Placed on the board at distance of 1 m from Rope A

Let and be the Tension in the rope at side A and B

Now Taking moment about

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move.
