3 dni temu · Watch this video to learn how to solve for a horizontally-launched projectile, with no initial y-component to velocity.
4 dni temu · Consider the motion under gravity of a bob of mass m attached to a fixed point by an inextensible massless rod of length ℓ. The bob is free to move on a sphere of radius ℓ. Using spherical coordinates (angles) θ and ϕ as the generalized coordinates, the kinetic and potential energies become.
5 dni temu · A projection is a linear transformation P (or matrix P corresponding to this transformation in an appropriate basis) from a vector space to itself such that P2 = P. That is, whenever P is applied twice to any vector, it gives the same result as if it were applied once (idempotent).
