Consider a car is travelling for one hour. Which of the following cases has the greatest average velocity in the east-direction?
Correct answer: C. Car travels 70 km due east
- A. Car travels 20 km due east
- B. Car travels 20 km due east, then turns around and travels 40 km due west
- C. Car travels 70 km due east
- D. Car travels 30 km due west, then turns around and travels 30 km due east
Explanation
Average velocity = total displacement / total timeAs the time is same, so averge velocity will depend on total displacemnent.AVERAGE VELOCITY ∝ TOTAL DISPLACEMENTAs, the maxiumum displacement is in option C , so this is right option

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.
