(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. Homework 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= .14i need help
