4. A girl places a stick at an angle of 60.0° against a flat rock on a frozen pond. She pushes at an angle and moves the rock horizontally for 2.00 m across the pond at a velocity of 4.00 m/s and power of 160.0 W. What force did she apply to the stick? How much work did she do? Your response should include all of your work and a free-body diagram.

I will reward brainliest to whoever gives the Work, Force, and a general idea of what the freebody diagram should look like.
