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