Definitions and Equations: Moment of Inertia (D): Tendency to resist angular acceleration; the angular equivalent of mass. In practical terms it is a measure of how hard it is to rotate an object or segment, like a baseball bat or a body segment. It is the sum of the products of the mass (m) with the square of its distance from the axis of rotation (ka). SEE FINAL TWO PAGES OF THIS LAB EOR CHARTS NEEDED TO CALCULATE L. 1...
*See the HINT file for help with the question below. 6. Jamie, a baseball player, sets up in the batting box and holds his bat still over the plate for a moment. Jamie holds the 0.91 kg bat in a horizontal position with only one hand. The hand is 10 cm from the knob end of the bat. The bat is 89 cm long, and its center of gravity is 60 cm from the knob end of the bat. a....
A baseball player swings a bat. The bat is 1.5m from the fulcrum (axis of rotation) to the top of the bat. The start angle of the swing is 70° and the angle at which the ball is hit is 190°. The start time is 0s and the end time is 0.5s. The bat swings in the negative direction. What is the linear distance traveled by the end (top) of the bat?
6. Calculate the moment of inertia of a baseball bat about the handle (in kgm) given that the mass is 5kg and radius of gyration is 20 cm.
2. Where is the trademark of a baseball bat, ``sweet spot'' of a tennis racket (or cricket bat), etc? If you've played baseball, you know there is a wrong way to hit the ball. If the ball hits the end of the bat or too close to your hands it stings your hands, but if you hit it ``on the trademark'' you get better power and your hands don't hurt. Both are true because the bat is pivoting around your...
The dogs model a baseball bat as a rod of increasing linear mass density that goes as: λ = 1.2x moment of inertia if the bat is length L and it is swung about the low density end? (b) What is the moment of inertia if it is swung about an axis that is 0.1L away from the low density end? 2. . (a) what is the

In the figure, two particles, each with mass m = 0.85 kg, are fastened to each other, and to a rotation axis at O, by two thin rods, each with length d = 5.4 cm and mass M = 1.1 kg. The combination rotates around the rotation axis with angular speed ω = 0.26 rad/s. Measured about O, what is the combination's (a) rotational inertia and (b) kinetic energy?
A physical pendulum of 1 kg of mass oscillates in a simple harmonic movement, with a period of π sec. The distance from the center of mass to the axis of rotation is 40 cm. What is your moment of inertia with respect to the center of mass? (consider g = 10 m/s^2)? a) 0.66 kg•m2 b) 1 kg•m2 c) 0.46 kg•m2 d) 0.84 kg•m2 e) 1.16 kg•m2
6. (BONUS) Two particles each with mass m = 0.4 kg, are fastened to each other, and to a rotation axis at 0, by the two thin rods, each of length d and mass M = 1.5 kg as shown below. The combination rotates around the rotation axis with angular speed w = 0.2 rad/s. The total moment of inertia of the system measured about O is 2.3 x 10-4 kg m?. (Hint: The moment of inertia of a thin...
Figure 1:Part A: A baseball bat can be rotated around many different axes of rotation. Three such possibilities are shown in (Figure 1) . Rank the baseball bat's moment of inertia about each of these three axes of rotation.Rank the moment of inertia from largest to smallest and overlap axes labels if the same.Part B: Given the same baseball bat and possible axes of rotation shown in (Figure 1) , for which axis of rotation would it be the easiest...
