Homework Statement Consider the diagram shown below of a flagpole of length, h. The flag is blowing in the wind exerting a force, F, horizontally on the flagpole a distance of 0.8h above the ground. The flagpole itself is hinged at the bottom and is kept upright by a light, inextensible...

I missed the class on The parallel axis theorem, and now I looked it on the wikipedia website, I don't understand it.

Also, please give me some hints about the second problem, thanks

I am not sure about the formula BUT..here is what I think should work..please tell me if its correct a(centripetal)= w^2 r

What is the radial component? I don't understand. Is that the centripetal acceleration?

For the 2nd question I have no clue, so please give some hints, so I can get something going in my head.

Hey! Sorry about that..but here it goes.. a(tangential) = wr = 11.1m x 0.5 rad/s^2 =5.55 m/s^2 Then I used the formula v=v0 + at v= at v= 5.55 m/s^2 x t t= 9.6 m/s^2 / 5.55 m/s^2 t= 1.73 t/2 because it asks for the deceleration half way through the curve Then I used the v=at again...

Homework Statement A car turns a corner with a radius of curvature of 11.1 m while braking to reduce its speed. If the brakes generate an angular deceleration of 0.5 rad/s2 what is the magnitude of the acceleration of the car half way through the corner when the car's linear speed is 9.6 m/s...
