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.
Migraine is a neurological disease and attacks can last four to 72 hours with sometimes severe pain that can be accompanied by other uncomfortable symptoms, including nausea, vomiting and light and noise sensitivity. It's long and it's really debilitating and so it's different than a tension-type headache, Buse says.
