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.

An electron and a proton are held on an x axis, with the electron at x = + 1.000 m and the proton at x = - 1.000 m. part a how much work is required to bring an additional electron from infinity to the origin? express your answer with the appropriate units. part b if, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial velocity of 100.0 m/s toward the origin, does it reach the origin? part c how close to the origin does it come?
