Three identical blocks of mass m take different paths from height h to reach the ground, as shown above. Block A is released from rest, while blocks B and C are released with velocity vor block B above the horizontal and block C horizontally.

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
