2 criticalF m 2m2 A) For a frictionless system, resonance occurs when the system is driven at the natural frequency wo vk/m. If we take the friction out of the spring-mass system. we're studying, we have m 1 and k 26 still. Calculate the natural frequency of this frictionless system, compare it to the critical driving frequency for the system with friction included, and draw a conclusion about the effect of friction on the frequency at which resonance occurs.
