COMEDK · Physics · 3. Motion In One Dimension
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 500 m
- B 250 m
- C 100 m
- D 200 m
Answer & Solution
Correct Answer
(B) 250 m
Step-by-step Solution
Detailed explanation
Speed of car, \(v=180 \mathrm{kmh}^{-1}=50 \mathrm{~ms}^{-1}\) and time, \(t=10 \mathrm{~s}\) \(\therefore\) Acceleration of the car, \(a=\frac{v-u}{t}=\frac{50-0}{10}=5 \mathrm{~ms}^{-2}\) Thus, the distance covered by the car,…
