A mass gains a speed of 28.2 cm/s when it is released from rest at the free end of a spring that is compressed by 3.20 cm horizontally. If the mass is now connected to the free end of the spring to form a mass-spring system, what is the period of this harmonic oscillator?

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
