NDA 2017 Physics question
The speed of a car travelling on a straight road is listed below at successive intervals of 1 s : Time (s) : 0, 1, 2, 3, 4 Speed (m/s) : 0, 2, 4, 6, 8 Which of the following is/are correct ? The car travels 1. with uniform acceleration of . 2. 16 m in 4 s. 3. with an average speed of 4 m/s. Select the correct answer using the code given below :
Answer: (A)
Solution
The speed rises by 2 m/s in every second, so the acceleration is uniform and equal to (statement 1). Distance in 4 s: $s = ut +
