Physics

An 80 kg man stands in a very strong wind moving at 15 m/s attorso height. As you know, he will need to lean in to the wind, andwe can model the situation to see why. Assume that the man has amass of 80 kg, with a center of gravity 1.0 m above the ground. Theaction of the wind on his torso, which we approximate as a cylinder50 cm wide and 90 cm long centered 1.2 m above the ground, producesa force that tries to tip him over backward. To keep from fallingover, he must lean forward.

Part A

What is the magnitude of the torque provided by the wind force?Take the pivot point at his feet. Assume that he is standingvertically. Assume that the air is at standard temperature andpressure.

Express your answer with the appropriate units.

For Part A. I tried 72.9 degrees, 85.02 degrees and 234.44 (I'mdesperate)

Part B

At what angle to the vertical must the man lean to provide agravitational torque that is equal to this torque due to the windforce?

Express your answer in degrees.

For part B. I already tried 5.25 degrees, 5.5 degrees and 6.5degrees

I need help please!!!!
