So far in your life, you may have assumed that as you are sitting in your chair right now, you are not accelerating. However, this picture is not quite complete! You are on the surface of the Earth, which is rotating. 1. a) What is the acceleration of a person sitting in a chair on the equator? b) The latitude of Corvallis is 44.4". What is your acceleration while sitting in your chair? (c) Is your apparent weight greater than,...

a) Is your mass times the gravitational acceleration of the Earth greater than, less than, or equal to the normal force exerted on you by the chair you are sitting on? Explain. b) A classmate of yours asks you why we have ignored this acceleration for the whole first term of physics. “Is everything we’ve learned a lie?” they ask. Assuage their fears by calculating the percent- age difference between the normal force from the chair and your weight.

a. Compute the centripetal acceleration of a point on the surface of the Earth at the equator caused by the rotation of the Earth about its axis. Enter the magnitude. The radius of the Earth is 6,371 km. The period is one day. m/s2 b. Suppose the Earth were spinning much faster. Find the period that results in the centipetal acceleration being equal to 9.8 m/s?. minutes When the centripetal acceleration equals the acceleration due to gravity, objects are in...

1) Consider a system consisting of your instructor sitting on a stool while holding weights in his hands. The stool can spin; it rotates at a rate of 26 RPM. The instructor holds masses in each hand. When his arms are fully extended, the total rotational inertia of the system is 4.5 kg · m2. He then moves his arms close to his body, reducing the total rotational inertia to 1.5 kg · m2. If there are no external torques,...

While standing stationary and writing on a patient’s chart, a doctor drops her pen. What can we say about the pen’s motion after she drops it? Ignore air resistance. A. Its velocity is constant. B. The magnitude of its velocity is decreasing. C. The magnitude of its acceleration is increasing. D. Its acceleration is constant. Janelle throws a 0.20 kg apple directly upwards with initial speed 16 m/s. Assuming we can ignore air resistance, what will be the height of...

In a judo foot-sweep move, you sweep your opponent's left foot
out from under him while pulling on his gi (uniform) toward that
side. As a result, your opponent rotates around his right foot and
onto the mat. The figure shows a simplified diagram of your
opponent as you face him, with his left foot swept out. The
rotational axis is through point O. The gravitational
force F→g on him effectively acts at his center of mass, which is a...

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...
