If you equate that equation with $F=ma$ and divide both sides by $m$, you get that the car's acceleration in the forward direction is. $$a=g \sin\theta\ -\ g C_{rr}\cos\theta\ - \frac{ \rho v^2 C_D A}{2 m}\ .$$. According to that equation, if $m$ increases, so does $a$.share | cite | improve this answer.f you equate that equation with $F=ma$ and divide both sides by $m$, you get that the car's acceleration in the forward direction is. $$a=g \sin\theta\ -\ g C_{rr}\cos\theta\ - \frac{ \rho v^2 C_D A}{2 m}\ .$$.

A typical migraine headache lasts less than 24 hours. Less commonly, a migraine can be as brief as 20 minutes or last for weeks. Generally, a migraine sufferer has headache-free periods between attacks. Tension-type headache can persist for days, weeks, or sometimes years. Cluster headaches are very intense but brief, usually lasting 30-90 minutes and repeating two to six times a day during a cluster episode.
