A child pushes a toy box 4.0 m along the floor with a force of 6.00 N directed downward at an angle 37.0 degrees to the horizontal. (a)How much work does the child do? (b)Would you expect more or less work to be done if the child pulled upward at the same angle?
try asking for help, not the answer.
What have you tried so far?
I think you should be able to see that pushing on the object adds an additional downward force, while pulling at the same angle lessens the downward force. Draw a diagram and label the forces acting on the box.
You need to use F=m*a and W=F*d
Learning formulas is part of physics, so study those.
