A "sun yacht" is a spacecraft with a large sail that is pushed by sunlight. Although such a push is tiny in everyday circumstances, it can be large enough to send the spacecraft outward from the Sun on a cost-free but slow trip. Assume that the spacecraft has a mass of 1100 kilogram and receives a push of 11 Newton.
(a) Find the magnitude of the resulting acceleration?
______m/s2
(b) If the craft starts from rest, determine how far will it travel in one day?
_____m
(c) Determine how fast will it then be moving?
______ m/s
