For a 25 kg object to have the same momentum as a 5kg object, the 25kg object must have

a. a greater velocity than the 5 kg object

b. a smaller velocity than the 5kg object

c. the same velocity as the 5kg object

d. not enough information to determine

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
