Displacement: Consider a deer that runs from point A to point B. The distance the deer runs can be greater than the magnitude of

Answer:
The given statement concerning distance and displacement is true.
Explanation:
If any point travels along any path between two points A and B the distance it travels is the length of the actual path it travels.
Mathematically the distance between two points is the algebraic sum of the infinitesimal distances that the particle travels.
Mathematically
Displacement by definition is the shortest distance between the initial and final positions of the particle and is given by the straight line joining the two points.
Since a line is the shortest path that exists between 2 points thus it will be always smaller than any other path connecting the 2 points hence will be smaller than the distance.
While as if the object travels along a straight line without changing it's direction the distance in that case equals the displacement.

Answer:
The acceleration is:
Explanation:
To answer this, we need to recall Newton's Second Law of motion, that states that an object of mass m would accelerate (change its state of uniform motion) proportional to the force (F) that is applied , and exemplified by the following equation:
From here, and using the given values for mass (m = 3 kg) and force (F = 9 N), we can derive the value of the acceleration as shown below (notice that since all quantities are given in SI units, the resulting acceleration will also be in Si units ():
