iii). Given that the cuboid has a mass of 700 g , Find its density in \( \mathrm{Kgm}^{-3} \)

3.33 • Uma canoa tem velocidade de \( 0,40 \mathrm{~m} / \mathrm{s} \) a sudeste em relação à Terra. A canoa se desloca em um rio que escoa a \( 0,50 \mathrm{~m} / \mathrm{s} \) para leste em relação à Terra. Determine o módulo, a direção e o sentido da velocidade da canoa em relação ao rio.

10. The distance travelled by a free falling object varies directly to the square of the time taken. Given that an object dropped a distance of 19.6 m after 2 seconds, find the distance dropped after 5 seconds.

24. Let \( |\vec{A}|=150 N \) and the vector \( \vec{A} \) makes an angle of \( 60^{\circ} \) with the positive y axis. Let P be the scalar projection of \( \vec{A} \) on to the xz plane and it makes an angle of \( 30^{\circ} \) with the positive x axis. Express vector \( \vec{A} \) in terms of its rectangular \( (\mathrm{x}, \mathrm{y}, \mathrm{z}) \) components;

Describe the law of conservation of momentum as it pertains to a real-life scenario, and explain how it applies. Begin by identifying the real-life scenario. You may start your response with: - A real-life scenario pertaining to conservation of momentum is ... - In this scenario, the law of conservation of energy applies because . . .

7. Let vectors \( \vec{A}=2 i-3 j \) and an unknown vector \( \vec{B} \) lie on the xy plane, where \( \vec{A} \cdot \vec{B}=4 \) and \( |\vec{A} \times \vec{B}|=4 \) a) Find the angle \( \theta \) between the two vectors b) Find \( \vec{B} \) and express it in terms of rectangular unit vectors
