Physics · MOTION IN A STRAIGHT LINE
हिन्दीA player throws a ball vertically upwards with an initial speed of \( 29.4\text{ m s}^{-1} \). Assuming acceleration due to gravity \( g = 9.8\text{ m s}^{-2} \), what are the maximum height attained by the ball and the total time taken by the ball to return to the player's hands?
Correct answer · Option 2
\( 44.1\text{ m} \) and \( 6.0\text{ s} \)
Explanation
Maximum height \( H = \frac{u^2}{2g} = \frac{(29.4)^2}{2 \times 9.8} = 44.1\text{ m} \). Time of flight \( T = \frac{2u}{g} = \frac{2 \times 29.4}{9.8} = 6.0\text{ s} \).
