just wanted to double check with you on a webassign question. i feel like i'm doing it right but webassign doesn't like my answer... question 2 says 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. Suppose that the spacecraft has a mass of 1100 kg and receives a push of 17 N.(adsbygoogle = window.adsbygoogle || []).push({});

(a) What is the magnitude of the resulting acceleration?

17/1100= 0.015 or 1.5e-2 but webassign says its wrong

(b) If the craft starts from rest, how far will it travel in 1 day?

change in x=vo(change in t)+1/2a(change in t)^2

=1/2(0.015)(24)(3600)^2

=5.6e7

(c) How fast will it then be moving?

but then again if the acceleration magnitude is wrong then part b equation wouldn't work. i'm also unsure how to do part c. let me know your thoughts. thanks
