A race car accelerates uniformly as it leaves the pit area, going from rest to 330 km/h in a semicircular arc with a radius of 200 meter.
Estimate the radial acceleration of car at this time.
m/s2
If the curve were flat, find what would the coefficient of static friction have to be between the tires and the roadbed to provide this acceleration with no slipping or skidding?
A 130 resistor, a 5.00×10?2microF capacitor, and a 260mF inductor are connected in series to a voltage source with amplitude 240 V. What is the maximum voltage across the inductor at resonance
