AP EAPCET 2024 - 22th May Evening Shift | Motion in a Plane Question 4 | Physics

A ball at point $O$ is at a horizontal distance of 7 m from a wall. On the wall a target is set at point $C$. If the ball is throw from $O$ at an angle $37^{\circ}$ with horizontal aiming the target $C$. But it hits the wall at point $D$ which is at a vertical distance $y_0$ below $C$. If the initial velocity of the ball is $15 \mathrm{~ms}^{-1}$. Find $y_0\left(\right.$ given, $\left.\cos 37^{\circ}=\frac{4}{5}\right)$ AP EAPCET 2024 - 22th May Evening Shift Physics - Motion in a Plane Question 3 English
