of 220 ns duration at a small 8 mg pellet at

rest. The pulse hits the mass squarely in the

center of its bottom side.

The speed of light is 3 × 108 m/s and the

acceleration of gravity is 9.8 m/s2.

If the radiation is completely absorbed

without other effects, what is the maximum

height the mass reaches?

Answer in units of μm.

Pressure*Area = Force = ma

F = dp/dt

p = E/c

I'm not even sure where to start. I guess I need to figure out the relation between Power and energy to get the momentum. From that I can get the force and then acceleration, etc...

Any hints would be appreciated
