Kinetic Energy Formula:
`\displaystyle KE = (1)/(2)mv^2`

• Energy is in Joules
• m is mass (in kg)
• v is velocity (in m/s)

Step-by-step explanation:

Step 1: Define

m = 20 kg

v = 10 m/s

Step 2: Find KE

1. Substitute [KE]:
   `\displaystyle KE = (1)/(2)(20)(10)^2`
2. Exponents:
   `\displaystyle KE = (1)/(2)(20)(100)`
3. Multiply:
   `\displaystyle KE = (10)(100)`
4. Multiply:
   `\displaystyle KE = 1000`
