Standard solar panels transform 3,600,000 J of input light energy into 720,000 J of useful electrical energy. The new solar panels that mimic butterfly wings are thought to have double the energy efficiency. Calculate the energy efficiency of the new solar panel improved through biomimicry.

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
