A person travels along a straight road for the first half time with a velocity V1 and the second half time with a velocity V2 .Then the mean velocity v is given by
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Displacement in the 1st half time = v1t Displacement in the 2nd half time = v2t and use simple formula to find mean velocity/average velocity which is equal to total displacement/time

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.
