A cart of mass 3.0 kg experiences four forces: 30 N upward, 30 N downward, 12.0 N to the left and 9.0 N to the right as the cart rolls across the table. What is the resulting acceleration of the cart? a
7.0 m/s2 to the left

b
4.0 m/s2 to the left

c
1.0 m/s2 to the left

d
27 m/s2 to the left

e
3.0 m/s2 to the right

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
