the normal force is the weight of the bag .... it would be nice to know if 27 is the maximum force need to start the bag moving

anonymous · Answer

i know these kind of questions make me mad because it doesnt have alot of info

amistre64 · Answer

120 * .23 = 27.6

and 117 is close to 120 so i guess thats the most correct choice
