The following diagram shows the path of a planet around the Sun. Kepler discovered that _. the distance from P 3 to P 4 equals the distance from P 4 to P 5 area D = area B + area C the distance from P 4 to P 5 equals the distance from P 6 to P 1 the speed in the interval from P 4 to P 5 equals the speed in the interval from P 1 to P 2

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
