Problem 1: The velocity of a particle moving along the x-axis varies
according to the expression vx = (40 – 5t 2) m/s, where
t is in seconds.
Find the average acceleration in the time interval
t=0 to t= 2.0 s.

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
