(a) What is the asteroid's acceleration in unit-vector notation?

__m/s2 i + __m/s2 j

(b) What is the asteroid's acceleration as a magnitude and direction?

__m/s2

__° (counterclockwise from the +x axis is positive)

2. Relevant equations

W= F * d

3. a) 55/85 m/s2 i + (32 cos 30-40 cos 60)/85 m/s2 j

= 0.65 m/s2 i + 0.091 m/s2 j

b) (.65^2 +.091^2) ^.5 is the net acceleration.

for direction i used tan x=.091/.65

answer= .14

i need help
