Aprojectile is fired from point 0 at the edge of a cliff, with initial velocity components of v(ox)= 60 m/s and v(oy)= 175 m/s. the projectile rises and then falls into the sea at point p. the time of flight of the projectile is 40.0 s, and it experiences no appreciable air resistance in flight. what is the magnitude of the velocity of the projectile 21.0 s after it is fired?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
