Displacement vectors of 6 km South 2 km North, 7 km South, and 5 km North combine to a total displacement of 6 km South.
Answer: Option A
<u>Explanation:</u>
The displacement vector represents the location change: the distance of separation from the start point to the end point is the displacement vector’ magnitude, and travelled direction denotes the displacement vector’ direction.
In figure, the illustration shows a new vector for the entire journey from beginning to end. In other words, C = A + B. The C vector is called the sum, or resultant vectors. When applying this concept to the given question, we can find the total displacement vector value. It is as follows:
Given:
6 km South 2 km North, 7 km South, and 5 km North
Total displacement, s = 6 km South - 2 km North + 7 km South - 5 km North
North and south lie in an opposite direction. Therefore, when combining all distances negative sign mentioned to denote the direction.
Total displacement, s = 13 km South - 7 km North
Total displacement, s = 6 km South

someone to check if the answer is correct
Speed of particle B is 2v₀/3 m/s to the left. Particle A and particle B will always have equal speed since they experience equal forces.
<h3>Conservation of energy</h3>
The speed and direction of the particle B is determined by applying the principle of conservation of energy as follows;
K.E₁ + P.E₁ = K.E₂ + P.E₂
At any given position, the speed of particle A and particle B will be equal, since they experience equal force and they have equal masses.
The complete question is below:
Particle A and particle B, each of mass M, move along the x-axis exerting a force on each other. The potential energy of the system of two particles assosicated with the force is given by the equation U=G/r 2, where r is the distance between the two particles and G is a positive constant. At time t=T1 particle A is observed to be traveling with speed 2vo/3 to the left. The speed and direction of motion of particle B is ?

Explanation:
Let be the mass of sled and children before impact.
Let be the mass of sled,children and their father.
Let be the velocity before impact.
Let be the velocity after impact.
The momentum can be conserved because there are no external forces that can affect the momentum.
This is a inelastic collision.
