Question 1

A wheel rotating about a fixed axis has an angular position given by θ = 3.0 − 2.0t3, where θ is measured in radians and t in seconds. What is the angular acceleration of the wheel at t = 2.0 s?

◦
−1.0 rad/s2

◦
−24 rad/s2

◦
−2.0 rad/s2

◦
−4.0 rad/s2

◦
−3.5 rad/s2


Question 2

A wheel rotating about a fixed axis with a constant angular acceleration of 2.0 rad/s2 turns through 2.4 revolutions during a 2.0-s time interval. What is the angular velocity at the end of this time interval?

◦
9.5 rad/s

◦
9.7 rad/s

◦
9.3 rad/s

◦
9.1 rad/s

◦
8.8 rad/s

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids.
