Why do dogs like to use fire hydrants and related items as objects of relief?
1) The artillery shell has a horizontal velocity of 172.073 m/s. 300 * cos(55) 172.073 During the 42 second interval, the shell travels a horizontal distance of 7,227.063 meters. 172.073 * 42 7,227.063 This is the x-coordinate. The artillery shell has a vertical velocity of 245.746 m/s. 300 * sin(55) 245.746 At the end of the 42 second interval, the projectile's altitude is 1,677.716 meters. 245.746 * 42 + 1/2(-9.8) * 42^2 1,677.716 This is the y-coordinate. 2) Multiply the initial velocity by the cosine of the launch angle to calculate the horizontal component of the initial velocity vector. Multiply the initial velocity by the sine of the launch angle to calculate the vertical component of the initial velocity vector. Divide the horizontal distance, d, by the horizontal component of the launch vector to find the transit time, t. Insert the vertical component and the transit time into the following equation: height v(i)t + 1/2(-9.8)t^2 where: v(i) the vertical component of the initial velocity vector, t the elapsed time, -9.8 downward acceleration due to gravity. This gives the height at the end of time interval t. The equation above assumes a launch altitude of zero. If the projectile is launched from an elevated position, simply modify the equation as follows: height h(i) + v(i)t + 1/2(-9.8)t^2, where h(i) the initial height at launch.

RE: Sound proofing a room with egg cartons? so i want to know how many egg cartons should i put in my walls? i have 1 window and 1 door and my room is very small too but is there also others ways to attached egg cartons in wall insteas of stapling? its my bed room roo so i dont wanna ruin my walls plus ill just put the egg cartons everytime
Collect as many egg cartons as you can find. It's a good idea to measure the space you want to soundproof and keep a track of the square footage of the cartons you collect. Ask friends and family to save their used egg cartons and approach local stores or farms that sell loose eggs to see if you might be able to commandeer their castoffs. It's not necessary to increase your intake of eggs, as you'll be surprised how quickly you'll accumulate what you need. Remember you'll need to account for the ceiling of the room you want to soundproof. It's a good idea to make sure you have an excess of what you'll need to cover the whole area in case of errors. Glue your egg cartons together to make larger tiles. Make sure these aren't too big for you to handle as you'll need to get these onto your walls and ceilings. Apply a generous amount of adhesive to the outside edge of each carton and stick together leaving no gap. If you have collected enough egg cartons, it's a good idea to double the thickness of your soundproofing by sticking cartons together to make two layers. Nail or pin your egg cartons to the wall and ceiling. Glue the egg carton tiles you've made together to seal as you go to make sure there are no gaps through which sound can escape. Make sure you cover any doors or windows in the room. Nail or pin the blankets over the egg cartons to increase the absorption of sound. Block any gaps around doors or windows with material. Turn your music up and note how many fewer complaints, if any, you receive.
