a worker pushes a 7kg shipping box along a roller track. assume friction is small enough to be ignored because of the rollers. the worker's push is 25 N directed down and to the right at an angle of 20 degrees.

1. determine the horizontal component of the worker's push

2. write a net force equation for the horizontal forces on the box

3. determine the acceleration of the box

4. determine the normal force on the box
