a 2.00 kg mass is connected to a spring with a spring constant of 9.00 N/m. THe displacement is given by the expression x(t) = 12.0 cm sin(w t). What is the max velocity of the simple harmonic motion?
An antiproton (same properties as a proton except that q = -e) is moving in the combined electric and magnetic fields of the figure below, in which 1050 V/m is the magnitude of the electric field (directed down) and 466 m/s is the antiproton's speed ..
