Work is done when a motion resulted from the force being done by an object. The amount of work done is calculated by multiplying the force applied and the distance traveled. It is calculated as follows:
Work = Force x distance = 280 N x 5 m = 1400 J.
Answer:
<em>(a) t = 4.52 sec</em>
<em>(b) X = 1,156.49 m</em>
Explanation:
<u>Horizontal Launching
</u>
If an object is launched horizontally, its initial speed is zero in the y-coordinate and the horizontal component of the velocity
remains the same in time. The distance x is computed as
.
(a)
The vertical component of the velocity
starts from zero and gradually starts to increase due to the acceleration of gravity as follows

This means the vertical height is computed by

Where
is the initial height. Our fighter bomber is 100 m high, so we can compute the time the bomb needs to reach the ground by solving the above equation for t knowing h=0


(b)
We now compute the horizontal distance knowing 

Option C is the right answer
-- The product of the magnitudes of the two charges.
-- The distance between the centers of the two charges.
The signs of the charges ... whether their signs are the same
or opposite ... determines the direction of the forces, but not
their magnitude.
