A stone falls freely under gravity. It covers distance, and, in the first , seconds, and the next, seconds respectively. The ratio is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Use the second equation of kinematics, in the above question, h=ut+12gt2 in the first 4 second the distance travelled by stone, d1=h4=0+12g42=8g, and the distance travelled in 12 seconds, d2=h12-h4=12g122-12g42=64g, the ratio, d2d1=648=8.
