2 AnswersMathematics7 months agoThree small children are pulling a rag doll in different directions, each trying to get the doll from the other two.?
The x-component of the force exerted by the first child is 5.0 N, and the
y-component is 3.0 N. The second child’s force is -4.0 N in the x-direction and 2.0 N in the y-direction. The x- and y- directions of the third force are 1.0 N and -8.0 N. What are the components of the net force acting on the rag doll? What is the direction and magnitude of the net force?
