z = 1/2gt^2
x = v^2sin2(theta)/g
pretty sure we don't need y in this case. am i along the right lines? still not sure how to get what they got using these
I was using an equation of motion which relates the acceleration in the Earth's rotating frame and a non moving frame and i tried to intergrate it to get the answer they wanted
a = a' - 2wXv' + wX(wXx')
where a, a', w, v' and x' are vectors and X is the cross product

The image above shows the question I'm stuck on.
I've done the first part and got the force per unit mass to be -2wV'cos\lambda
But I have no idea how to get the equation for the eastward displacement due to the Coreolis.
Any...
1. A rigid straight uniform bar of mass m and length l is attached by a frictionless hinge
at one end to a fixed wall so that it can move in a vertical plane. At a distance a from
the hinge it is supported by a spring of stiffness constant k, as shown in the figure
Ignoring gravitational...
Basically can a neutral pion go to two electrons and two positrons and under what interaction would it do this?
I know its defiantly not the strong force, so is it weak or EM? I'm pretty sure its EM but not 100%
Thanks
I am hoping to visit CERN at some point, but the underground areas are closed off at the moment. So just wondering if anyone knows when it's open to the public again
Thanks :)
I've been trying for a while now. I don't know how to relate \phi with the distance rolled down the plane. Could really use some help if you know anything that would help. Thanks
