When the bike is moving at 2 m/s, its kinetic energy is (1/2 m v2) = (5 x 4) = 20 joules.

When it's moving at 3 m/s, its kinetic energy is (1/2 m v2) = (5 x 9) = 45 joules.

The difference between initial KE and final KE is (45 - 20) = 25 joules.

That's how much work you have to do on it in order to increase its KE.

Q: How much work must be done on a 10 kilograms bicycle to increase its speed from 2 meters per second to 3 meters pe second?

There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.

0.2 meters per second in the direction opposite where he threw the wrench.

Angular momentum is defined as the cross product of a distance (from the axis of rotation) and a momentum, so you have to use units accordingly. In the SI, that would be meters x kilograms x meters / second, which you can simplify to meters squared x kilograms / second. This is equivalent to joules x seconds.
