(II) $\hat{\mathbf{v}}$ is a vector 24.8 units in magnitude and points at an angle of $23.4^{\circ}$ above the negative $x$ axis. $(a)$ Sketch this vector. (b) Calculate $V_{x}$ and $V_{y}-(c)$ Use $V_{x}$ and $V_{y}$ .to obtain (again) the magnitude and direction of $\vec{\mathbf{v}}$[Note. Part $(c)$ is a good way to check if you've resolved your vector correctly.

In physics, a rigid body is an object that is not deformed by the stress of external forces. The term "rigid body" is used in the context of classical mechanics, where it refers to a body that has no degrees of freedom and is completely described by its position and the forces applied to it. A rigid body is a special case of a solid body, and is one type of spatial body. The term "rigid body" is also used in the context of continuum mechanics, where it refers to a solid body that is deformed by external forces, but does not change in volume. In continuum mechanics, a rigid body is a continuous body that has no internal degrees of freedom. The term "rigid body" is also used in the context of quantum mechanics, where it refers to a body that cannot be squeezed into a smaller volume without changing its shape.

In physics, rotational dynamics is the study of the kinematics and kinetics of rotational motion, the motion of rigid bodies, and the about axes of the body. It can be divided into the study of torque and the study of angular velocity.

so here for party. We should sketch the vector so we can say that Begin drunk. Our X and Y axis says they're Y axis. This is our X axis. This would represent Visa X. This would represent a V supply. And then this vector here would represent the vector V. And we can say that this angle here is going to be 23.4 degrees. So that would be the sketch of the vector. We can say that for B. If we want to find R, v X and V, why we can save the X would be equal to negative 24.8 because it's in the negative direct negative X Direction Times Co sign of 23.4 degrees. This would equal negative 22.8 units for Visa. Why, this would be 20 positive 24.8, Because again, it's in the positive direction sign of 23.4 degrees. Uh, this is going to be 9.85 units and for part C, when we want to find the magnitude and thea the direction, we can say that the magnitude of Vector V would be equal to the sum of the squares to the the square root of the sum of the squares. So this would be negative. 22.8 squared plus 9.85 squared to the 1/2 power, and this should equal 24.8. This does, in fact, equal 24.8 units to find the direction this would be Fada equals R pan of the why component 9.85 divided by the x component 22.8 and this is giving us 23.4 degrees above negative x access. That is the end of the solution. Thank you for watching.
