AP EAMCET · PHYSICS · Motion In One Dimension
When a player thrown a ball, it reaches the other player in \(4 \mathrm{~s}\). If the height of each player is \(1.8 \mathrm{~m}\), the maximum height attained by the ball above the ground is
- A \(19.4 \mathrm{~m}\)
- B \(20.4 \mathrm{~m}\)
- C \(21.4 \mathrm{~m}\)
- D \(22.4 \mathrm{~m}\)
Answer & Solution
Correct Answer
(C) \(21.4 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Time taken to reach the ball from one player to another is equal to time of flight. Hence, time of flight, \(T=4 \mathrm{~s}\) \(\frac{2 u \sin \theta}{g}=4 \Rightarrow u \sin \theta=2 g\) ...(i) Height attained by the ball above the ground \(=\) height of either player +…
