AP EAPCET 2024 - 18th May Morning Shift | Motion in a Plane Question 9 | Physics

Ball is projected at an angle of $45^{\circ}$ with the horizontal．It passes through a wall of height $h$ at a horizontal distance $d_1$ from the point of profection and strikes the ground at a distance $d_1+d_2$ from the point of projection, then $h$ is :

$h=\frac{2 d d_2}{d_1+d_2}$

$h=\frac{d d_2}{d_1+d_2}$

$h=\frac{\sqrt{2} d d_2}{d_1+d_2}$

$h=\frac{d d_2}{2\left(d_1+d_2\right)}$

A force $$\mathbf{F}_1$$ of magnitude 4 N acts on an object of mass 1 kg , at origin in a direction $$30^{\circ}$$ above the positive $$X$$-axis. A second $$F_2$$ of magnitude 4 N acts on the same object in the direction of the positive $$Y$$-axis. The magnitude of the acceleration of the object is nearly.

$$6.9 \mathrm{~ms}^{-2}$$

$$7.6 \mathrm{~ms}^{-2}$$

$$4.3 \mathrm{~ms}^{-2}$$

$$8.0 \mathrm{~ms}^{-2}$$
