A water bomber flying horizontally with a velocity of 400 m/s at a height of 10 km above the ground drops a 400 kg water bomb.
*Note: Show all of your work/calculations
(a) Determine the total energy of the water bomb the instant it is released from the
airplane.
(b) Determine the kinetic energy of the water bomb the instant it has fallen half of its
original height
(c) Determine the kinetic energy and the speed of the water bomb just before it hits the
ground.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
