The front spring of a car‘s suspension system has a spring constant of 1.54×106 N/m and supports a mass of 243 kg. The wheel has a radius of 0.386 m. The car is traveling on a bumpy road, on which the distance between the bumps is equal to the circumference of the wheel. Due to resonance, the wheel starts to vibrate strongly when the car is traveling at a certain minimum linear speed. What is this speed ?
Yes, you can get lung cancer, throat cancer which is the worst and maybe even tongue cancer. The tar in cigarettes has alot of bad, very harmful chemicals. Ewww, would you drink a bottle of poison.
f 1/(2Pi)sqrt(k/m) f 1/(2Pi) sqrt(1 540 000/243) 12.67 Hz The wheel has circumference C 2PiR 2.43 m At 12.67 revolution per second (hz) this represents a linear speed of v 12.67 * 2.43 30.7 m/s 110 km/h
o Yes, all cigerattes cause health problems, even if they are non addictive, they are still cigerattes, just non addictive (so you wont have as many as with addictive ones)
