In simple harmonic motion, when is the magnitude of the acceleration the greatest? (There could be more than one correct choice.)
 
  A) when the kinetic energy is a minimum
  B) when the displacement is a zero
  C) when the speed is a maximum
  D) when the potential energy is a maximum
  E) when the magnitude of the displacement is a maximum

Question 2

A baseball pitcher is employing a ballistic pendulum to determine the speed of his fastball. A lump of clay is suspended from a cord 2.0 m long.
 
  When the pitcher throws his fastball aimed directly at the clay, the ball suddenly becomes embedded in the clay and the two swing up to a maximum height of 0.080 m. If the mass of the baseball is 0.21 kg, find the speed of the pitched ball.
