TS EAMCET · Physics · Motion In One Dimension
A ball thrown upwards vertically reaches a height \(25 \mathrm{~m}\) in \(1 \mathrm{~s}\). The ratio of total distance covered by the ball in time \(t=2 \mathrm{~s}\) and \(t=4 \mathrm{~s}\) is (Use, \(g=10 \mathrm{~m} / \mathrm{s}^2\) )
- A 1
- B \(\frac{4}{5}\)
- C \(\frac{2}{3}\)
- D \(\frac{3}{4}\)
Answer & Solution
Correct Answer
(B) \(\frac{4}{5}\)
Step-by-step Solution
Detailed explanation
Given that, the height achieved in \(1 \mathrm{~s}, h=25 \mathrm{~m}\) Let \(u\) be the initial velocity in upward direction. By equation of motion, \( h=u t-\frac{1}{2} g t^2 \)…
