Use acceleration forms and differential equations in rectilinear motion
Motion is along an oriented straight line. Position x is in metres, time t in seconds, velocity v=dx/dt in m/s and acceleration in m/s². Coefficients have the units required by their equations. Give exact values; logarithms are natural
\[v(x)=(-1)(3x+2),\qquad x=1\]
Use the differentiable position branch to find the listed quantities. The displayed velocity is nonzero at this position
