A car starts from rest and accelerates uniformly to a speed of \(180 \mathrm{~kmh}^{-1}\) in \(10 \mathrm{~s}\). The distance covered by the car in this time interval is
- A 100 m
- B 500 m
- C 200 m
- D 250 m
Answer & Solution
Correct Answer
(D) 250 m
Step-by-step Solution
Detailed explanation
The initial velocity \(u = 0\) m/s. The final velocity \(v = 180 \text{ kmh}^{-1}\). Converting \(v\) to m/s: \(v = 180 \times \dfrac{5}{18} = 50 \text{ m/s}\). The time interval \(t = 10 \text{ s}\). Since the acceleration is uniform, the average velocity is…
