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.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Aforce of 100 newtons is used to move an object a distance of 15 meters with a power of 50 watts. find the work dine and the time it takes to do the work
