Three uniform objects are located in x-y plane. A 10 kg rod of length 30 cm has its center located at x = 50cm. A 2kg spherical ball metal of radius 8cm has its center located at x = -50 cm. A spherical volleyball of 1 kg mass and 10cm radius has its center located at y =-30cm. The x- and y-coordinates of the center of mass of the three objects are:

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
