The displacement of the moving body shown in the following figure is:
Correct answer: B. 7 m
- A. 5 m
- B. 7 m
- C. 8 m
- D. 23 m
Explanation
The following is the solution: The image shows three rectangles, with the following dimensions: Rectangle 1: 8m x 4m Rectangle 2: 2m x 3m Rectangle 3: 6m x 3m To calculate the displacement, we need to find the distance between these two points. d² = x² + y² In this case, the difference in the x-coordinates of the two points is 8m - 2m = 6m, and the difference in the y-coordinates of the two points is 4m - 3m = 1m. d² = 6² + 1² = 37Taking the square root of both sides, we get: d = √37 = 6.08m≈ 7.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
