A baseball has a mass of 0.15 kg and radius 3.7 cm. In a baseball game, a pitcher throws the ball with a substantial spin so tha

seraphim [82]

Answer:

Explanation:

Given

mass of baseball $m=0.15 kg$

radius of ball $r=3.7 cm$

angular speed of ball $\omega =45 rad/s$

linear speed of ball $v=42 m/s$

Transnational Kinetic Energy is given by

$K.E.=\frac{mv^2}{2}$

$K.E.=\frac{1}{2}\times 0.15\times 42^2$

$k.E.=\frac{1}{2}\times 0.15\times 1764$

$k.E.=132.3 J$

Considering the ball as solid sphere its moment of inertia is given by

$I=\frac{2}{5}mr^2=\frac{2}{5}\times 0.15\times (0.037)^2$

$I=8.21\times 10^{-5} kg-m^2$

Rotational Kinetic Energy

$=\frac{1}{2}\times I\times \omega ^2$

$=\frac{1}{2}\times 8.21\times 10^{-5}\times 45^2$

$=\frac{1}{2}\times 8.21\times 10^{-5}\times 2025$

$=0.0831 J$

How is mass and inertia related

seraphim [82]

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Thepotemich [5.8K]

Answer:

Dependent variable.

Explanation:

Based on the description, the experiment is designed to confirm or reject a hypothesis about a heat absorption patterns by hollow objects with different transparency. Temperature appears to be the main target variable of interest - this is the dependent variable. Material that each box is made of (specifically, its transparency) is in this case the independent variable, which is determined by the experimenter.
