1. A force F causes a particle of mass m to move on the surface of an open
cylinder of radius R =
√x^2+y^2+z^2
(a) Write out the equations of motion of the particle in suitable coordinates.
(b) Construct a force F that causes the particle to perform simple harmonic motion
on the cylinder surface along the z-direction
I'm a little confused as to what the trajectory of the particle is...I'm assuming it is moving in circular motion around the cylinder but I'm not sure what the of the relevance of the open cylinder then.
If it is moving in circular motion, I was thinking the acceleration is just v^2/r perpendicular to the velocity (-r direction) but then since it is on a cylinder that would mean it wouldn't even move right?
