D. 12. 40.145 kg baseball is thrown with a velocity of 40m/s. How much kinelic energy does it have? 500J 116000 J 116 J 2900J

## Step 1<br />The problem involves calculating the kinetic energy of a baseball. The formula for kinetic energy is given by:<br />### **KE = \frac{1}{2}mv^2**<br />where \(m\) is the mass of the object and \(v\) is the velocity of the object.<br /><br />## Step 2<br />In this problem, the mass of the baseball (\(m\)) is given as 40.145 kg and the velocity (\(v\)) is given as 40 m/s.<br /><br />## Step 3<br />Substitute the given values into the formula to calculate the kinetic energy.
