The large blade of a helicopter is rotating in a horizontal circle. The length of the blade is 6.30 m, measured from its tip to the center of the circle. Find the ratio of the centripetal acceleration at the end of the blade to that which exists at a point located 4.43 m from the center of the circle.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particleâs motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energyâmomentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
