Tendons are, essentially, elastic cords stretched between two fixed ends; as such, they can support standing waves. these resonances can be undesirable. the achilles tendon connects the heel with a muscle in the calf. a woman has a 20-cm-long tendon with a cross-section area of 110 mm2 . the density of tendon tissue is 1100 kg/m3.

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
