The car being in motion really confused me, but that cleared everything up for me. Thank you.

First, just want to say Mastodon is the dang. Second, I'm assuming skidding means the force acting on the object exceeds the force of friction. To answer you Doc, I would say the kinetic friction. My problem is that the force of friction is acting perpendicular to the motion of the car itself...

1. A car travels around a circle with a diameter of 500m at a constant speed of 25 m/s. The static friction coefficient is 0.3 and the kinetic friction coefficient is 0.2. Will the car skid? 2. F = ma. Ffr = μmg. Centripetal acceleration = v2/radius3. So the math for this particular problem was...

1) Alright, so the problem reads, "The liquid in a horizontal pipe of diameter d1 before a constriction is at pressure P1 and flowing with the speed v1, and then in the constriction with diameter d2 the gauge measures pressure P2. What is the density of the liquid?" 2) I'm assuming the...
