Question 1

The National Aeronautics and Space Administration (NASA) has designed a spacecraft

powered by a light beam at 503 nm. The light is designed to make small corrections to the

vehicle's motion. The beam has a power of 64 watts and is powered by a long-lived nuclear

power source. The lightweight spacecraft only weighs 1.2 kg. Calculate the modified speed in

space (in m/s) due to the light beam after a 11 year flight with the light on.

Note: required precision is 1%.

Sanity check: the expected range is 4-300 [m/s]
