A motorist travelling at 72kmh−1 had his eyes shut for 0.4s during a hard sneeze. Calculate the distance covered by him during this time interval.
50.0m
28.8m
18.0m
8.0m
Correct answer is D
Convert velocity from kmh−1 to ms−1, by multiplying 10003600,
72×10003600 = 20ms−1
Therefore, distance covered in 0.4s = 20×0.4=8m
