A box has a force of 5 N that acts to the right. There is a second force of 10 N on the box acting to the left. What is the magnitude of the resultant force? *
you have the positive force meaning the right which is acting with 5 Newton's. The negative we can assume to be the 10 Newton's to the left if you subtract them the resultant force should be -5 so ,5 Newton's to the left
