Question

Showing all steps, derive and plot the velocity profile (i.e., $v(t)$) for constant $F_{TR}$-constant grade acceleration. (Constant grade means that $\beta$ is constant but not necessarily zero.) Given: 1. The EV starts from rest at $t = 0$. 2. Resultant of $F_{ext}$ and $F_{TR}$ is enough to overcome the rolling resistance to get the EV moving. 3. $v(t) \ge 0$ for $t \ge 0$. What effect does gravity have on the velocity profile?

Step 1

Step 1: First, we need to consider the equation for the Froude number (Fr), which is given by Fr = v / sqrt(g * L), where v is the velocity, g is the acceleration due to gravity, and L is the characteristic length. Show more…
