Explain how potential energy converts to kinetic energy in the loop-the-loop section of the rollercoaster. Make sure to note when the potential energy of the coaster is at its lowest in the loop-the-loop and when the kinetic energy of the coaster is at its highest. (Refer to the above diagram as needed)

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
