(III) The coefficient of kinetic friction $\mu_{\mathrm{k}}$ between twosurfaces is not strictly independent of the velocity of theobject. A possible expression for $\mu_{\mathrm{k}}$ for wood on wood is$$\mu_{\mathrm{k}}=\frac{0.20}{\left(1+0.0020 v^{2}\right)^{2}},$$where $v$ is in $\mathrm{m} / \mathrm{s} .$ A wooden block of mass 8.0 $\mathrm{kg}$ is at reston a wooden floor, and a constant horizontal force of 41 $\mathrm{N}$acts on the block. Use numerical integration to determineand graph $(a)$ the speed of the block, and $(b)$ its position, asa function of time from 0 to 5.0 $\mathrm{s}$ (c) Determine thepercent difference for the speed and position at 5.0 $\mathrm{s}$if $\mu_{\mathrm{k}}$ is constant and equal to $0.20 .$

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.
