You are about to shoot a shell with an artillery. You must decide which targets you can hit. Your muzzle velocity is 980 m/s and your shell is aerodynamic enough to ignore the drag.

  1. What is the maximum range if you are attempting to hit a target at the same elevation as you?
  2. What is the maximum range if you are attempting to hit a target that is 50 m below in elevation as you?
  3. What was the flight time for part b?
  4. Suppose your shell was to explode at the peak of its trajectory and break into two pieces. The first 1 kg is thrown with a speed of 400 m/s at an angle of 225 degrees from the forward direction (45 degrees into the third quadrant). What is the direction and the speed of the second piece if it has mass of 2 kg?
