A ball is projected from the ground with a speed of 25 m/s. Two seconds later it just clears a wall of height 5 m. Find a) the angle of projection b) the maximum height attained c) How far beyond the wall, the ball again hits the ground?
Solution: Given, Initial velocity of projection $\text{(u) = 25 m/s}$ In time $\text{t = 2 seconds}$, the ball clears a wall of height $\text{h = 5 m}$ Let us consider the acceleration due to gravity (g) be 10 m/s2 and $\theta$ be the angle of projection of the ball. We know, (a) For angle of…
