We can model a pine tree in the forest as having a compact canopy at the top of a relatively bare trunk. wind blowing on the top of the tree exerts a horizontal force, and thus a torque that can topple the tree if there is no opposing torque. suppose a tree's canopy presents an area of 9.0 m^2 to the wind centered at a height of 7.0 m above the ground. (these are reasonable values for forest trees.)
if the wind blows at 6.5 m/s, what is the magnitude of the drag force of the wind on the canopy? assume a drag coefficient of 0.50 and the density of air of 1.2 kg/m^3what torque does this force exert on the tree, measured about the point where the trunk meets the ground?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
