Catapult :: essays research papers

The RatapultObjective My objective in this interpret was to produce a wood pussy-trap powered catapult. It has a origin of 30 cm by 30 cm, and has a theme of cows trying to nonpayment the farm. The reason they want to escape is because they are being killed and turned into steaks, against in that respect will. That is why I developed this behindapult, to save the cows. The cows also cherished me to ask you to eat more chicken.Hypothesis and DrawingI hypothecate that if I build the ratapult to a 25-degree angle, and release the hacky straighten out at a height of .55m then there will be enough velocity to project the hacky ignition exactly four meters. The ratapult will release the hacky sack with an initial velocity of 5.8 m/s, and as a result the hacky sack will travel 4.0 meters in .75 seconds.ProcedureThe first step I took was to paint all of the wood white. After that I put wallpaper on the board that I am going to nail the rat trap to. I then attached the measuring c up to the rat trap by oil production a hole in the halfway of the measuring cup and then using string to attach the cup at both the drilled hole, and the hole at the bottom. Then I nailed the rat trap into the board with wallpaper. That board was then nailed into the base. Then I attached the go to the milk crate. The steps will hold the base of the ratapult at a 25-degree angle. I attached the steps by drilling holes in the bottom of them and then tying them to the milk crate. Then I nailed the board with wallpaper into the back end of the base. The base was then nailed into the steps, and glued grass decorations and cardboard cows to the base. The ratapult was completed.Data & ObservationsI found the initial velocity, or Vi, by finding the horizontal velocity, or Vx, and then using the equation Vx = Vi * cos(angle). The angle was 25 degrees, so I input that into the equation also. That made the equation look uniform5.3 m/s = Vi * cos(25)I divided both sides by sin(25), the n that gave me an initial velocity of 5.8 m/s. Then I inflexible to find the Vertical height of the hacky sack, so I used the equation Vy = Vi * sin(angle). Vy stands for initial vertical velocity.
