# Finding Kinetic energy

**1. The problem statement, all variables and given/known data**

If the velocity of a rocket is 10 meters per second and its mass is 10 kg, its kinetic energy is:

a. 5000 joules

b. 500 joules

c. 10000 joules

d. 1000 joules

[b]2. Relevant equations[/b)

Ek= (1/2) mv2

**3. The attempt at a solution**

e=(.5)10×10(2)

E=5000 j
