Answer:
Explanation:
Given:
- mass of bullet,
- initial velocity of bullet,
- displacement of the bullet in the target,
Here as given in the question the bullet penetrates the target by the given displacement of the bullet into it. During this process it faces deceleration and hence it comes to rest.
- so, final velocity of the bullet,
Now using the equation of motion:
where:
acceleration of the bullet
<u>Now the force of resistance offered by the target in stopping it:</u>
A plane has more mass in it. Also, the engine is very strong which it makes the plane able to push through the wind. When the wind is pushing, it goes by it because of the engine.
Answer:
The eyes collect and focus visible light. The lens and other structures of the eye work together to focus an image on the retina. ... Cells in the retina change the image to electrical signals that travel to the brain through the optic nerve. The brain interprets the electrical signals as shape, color, and brightness.
Explanation:
1) The distance travelled by the rocket can be found by using the basic relationship between speed (v), time (t) and distance (S):
Rearranging the equation, we can write
In this problem, v=14000 m/s and t=150 s, so the distance travelled by the rocket is
2) We can solve the second part of the problem by using the same formula we used previously. This time, t=300 s, so we have:
Taking care of hygiene, washing hands with soap and water
