Answer:
0.0483m or 48.3 mm
Explanation:
Let g = 10m/s2
At 8m, the pile has a potential energy of
P = mgh = 3000*10*8 = 240000 J
This energy is converted to kinetic energy once the pile drops down to the bottom:
Taking gravity into consideration, the net force acting on the pile once it hits the ground is
Therefore the net deceleration is:
We can find out how far it's driven into the ground with the following equation of motion:
where v = 0 is the final velocity, which is 0 because it stops, is the initial velocity when it hits the ground, a is the deceleration, and s is the distance it travels into the ground
or 48.3 mm
<h3><u>Answer;</u></h3>
the north end to the south end.
<h3><u>Explanation;</u></h3>
- Magnetic field lines from a bar magnet form lines that are closed. The direction of magnetic field is taken to be outward from the North pole of the magnet and in to the South pole of the magnet.
- A magnetic field refers to the area surrounding a magnet where a force is exerted on certain objects. These lines are spread out of the north end of the magnet.
- The magnetic field lines resemble a bubble.
Answer:
Explanation:
Aceleration is a change on the velocity of the object in a given time.
For this case: the initial velocity is
and the final velocity is :
so, the change in velocity is:
and the change in time , according to the problem:
So, the aceleration is:
