A man is in a car is moving with velocity of 36 km/hr. His speed with respect to the car is:
Correct answer: B. Zero
- A. 10 m/s
- B. Zero
- C. 36 km/hr
- D. Infinite
Explanation
The concept of relative velocity is key in this question. When two objects move together at the same speed, their relative velocity is zero. Here, the man and the car are both moving at 36 km/hr, so the man's speed with respect to the car is zero. Option A incorrectly suggests a relative speed of 10 m/s, while Option C incorrectly lists the car's absolute speed without considering its relation to the man. Option D suggests an infinite speed, which is not applicable. Therefore, the correct answer is Option B, as the relative velocity is indeed zero.

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.
