A man goes 10 towards North, then 20m towards east then displacement is
Correct answer: A. 22.36m
- A. 22.36m
- B. 25m
- C. 25.5m
- D. 30m
Explanation
The correct answer is 22.36m. Displacement is the shortest distance between the initial and final positions. Here, the man forms a right-angled triangle with legs of 10m north and 20m east. Using the Pythagorean theorem: Displacement = √(10² + 20²) = √(100 + 400) = √500 = 22.36m. Options B and C provide incorrect values that do not result from the correct calculation. Option D suggests the total path traveled, not the straight-line displacement.

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.
