The mass of a carbon atom is 2 x 10 ^ -26. What is the kinetic energy of a carbon atom moving with a speed of 500 m/s?
I got 2.5 x 10^-21 which is correct.

The second question states:

Two carbon atoms are joined by a spring-like carbon-carbon bond. The potential energy stored in the bond has the value calculated in part one if the bond is stretched 0.050nm. What is the bond's spring constant? Answer must be in N/m. Please help!
