In the given diagram, the displacement of the person is
Correct answer: C. +25 meters
- A. 0 meters
- B. -25 meters
- C. +25 meters
- D. 30 meters
Explanation
Displacement (Δx) = Final position (xf) - Initial position (xi)The final position (xf) and initial position (xi) can be represented as coordinates in a coordinate system, such as distance traveled along a straight line or a change in position in two or three dimensions.xf=8 secxi=4 sec - 2 secΔx = 50 - 25 = 25 Hence, the answer is 25 meters.

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.
