Question

​​​​A ram in the form of a rectangular body of size $l=9 \mathrm{~m}$ and $b=2 \mathrm{~m}$ is suspended by two parallel ropes of lengths $7 \mathrm{~m}$. Assume the center-of-mass of the body is at its geometric center and $g=9.81 \mathrm{~m} / \mathrm{s}^{2}$. For striking the object $\mathrm{P}$ with a horizontal velocity of $5 \mathrm{~m} / \mathrm{s}$, what is the angle $\theta$ with the vertical from which the ram should be released from rest?

• A. $67.1^{\circ}$
• B. $40.2^{\circ}$
• C. $35.1^{\circ}$
• D. $79.5^{\circ}$
