Plane Curvilinear Motion - n-t Coordinates - Example 3.3-2

 

Derive then following velocity magnitude equation with the help of the figure.

 

v = ρ(dθ/dt)

 

 

What is the general calculus equation for the velocity? Choose the one that is most appropriate for motion along a curved path.

 

v = dx/dt
v = ds/dt
v = a(t - t_o ) + v_o
