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. on *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. 1 А" В І 15 E % 3
List several other common devices that, like a stretched or compressed spring, can store potential energy when temporarily deformed. tion 1 A. B 1 = = CO
