One student wants to increase the potential energy of the marble at the starting position. Explain one way the students can adjust the track to increase the marble's potential energy. In your explanation, ​describe the dimensions of any materials used to adjust the track and
explain why the adjustment to the track would increase the marble's potential energy.

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
