The sulfate ion formula is SO42-
The kinetic energy that the given object will have is: 10 J
<h3>Kinetic Energy Calculation</h3>
We are given;
Mass of object; m = 4 kg
Speed of object; v = 5 m/s
Now, the formula for kinetic energy is;
K.E = ½mv²
Plugging in the relevant values gives;
K.E = ½ × 4 × 5
K.E = 10 J
