also I was always told to use this equation when the velocity is small through the medium Fd = -bv were this is just a proportion also that other formula that is suppose to be used when there is a high velocity Fd = 2^-1 p v^2 A Cd v Ok what is exactly meant by high and low ve...

so I got a question about projectile motion take the example of shooting of a plastic air rocket into the air and asked to predict its landing point and how high it goes... ok I know how to do this... the thing is now were not neglecting air resistence and I don't know wha...

I don't see how this relationship works Fn sin theta = r^-1 m v^2 or more like why it works??? my text goes on to prove tan theta = (rg)^-1 v^2 which I understand how to rearange I just don't get where the first relationship comes from Fn sin theta = r^-1 m v^2 i get i...

ok if a car is going around a bank curve my book is telling me there is an ideal spead were no friction is required at all for it to complete the banked turn it says that this occurs when the horizontal component of the normal force is equal to the radial acceleration why?

I'm trying to rearange this equation for Mu s That is the greek letter Mu subscript s... the static coeficent of friction m2 = m1 sin theta - Mu s m1 cos theta ok I got this Mu s = -((m1 cos theta)^-1 (m2 - m1 sin theta)) ok I know that sin over cosine is tangent but I can...

a wire has a resistance of 10 ohms. The length of the wire is doubled, and its radius is also doubled. What is the new resistance?

a block (mass m1) on a smooth horizontal surface, connected by a thin cord that passes over a pulley to as second block (m2), which hangs vertically. Ignore friction and the masses of the pulley and cord. If m1 = 13.0 kg and m2 = 6.0 kg determine the accleeration of each block...

I took algebra two and there not really verticle asymptotes threr limits you have been lied to which you should be used to if you are going to a public high school All I remeber is you try to get them to cancel out and get removable discontinuties or something this was a long ...

I think you mean the limits

thank you so much
