A motorcycle has initial velocity of 5 m/s. After 3 seconds, the velocity is 7 m/s The displacement of the motorcycle in 3 seconds is:
- A. 21 m
- B. 18 m ✓
- C. 36 m
- D. 6 m
Correct Answer: B. 18 m
Explanation
Displacement is calculated using the formula s = \frac{u+v}{2} \times t. Here, s = \frac{5+7}{2} \times 3 = 6 \times 3 = 18 meters.
