That's it, I'm putting down what I originally had as my answer:
"Plane's do not drop packages. If this plane dropped the package, then the package would be destroyed."
But, we could assume the package is dropped from an altitude of 900m?
That's what I had thought as well, that the height of the plane was fixed.
If i go with this approach, then the plane doesn't have two velocity components? Only one because the height is unchanging. Which would mean the package's velocity in the y component is due to gravity; it would be in...
I see what you are saying, in the initial velocity it gt is not involved, but AFTER it is dropped, yes.
I think I have worked out a solution.
Bare with me.
1. Vpack (y component) = Vplane*sinθ + gt
2. ((Vpack y)^2 - (Vpack nought y)^2)/(2g) = dy (altitude from which the package has to...
@lewando, the x axis would be the distance's between the nose of the plane and the rear of the ship. The y axis would be the difference in altitudes.
Okay, I drew a diagram
the velocity of the plane is given but it has an x and v component.
Vplane = 180 m/s
Thus the intial velocity...
A plane flies at 900m and has to deliver a package. It flies at 180 m/s North at 15° below the horizontal. The ships velocity is 40 m/s and it is travelling due north. At what horizontal distance from the ship must the package be dropped for it to land on the ship...
I have to derive an equation with the following variables:
and I was told to think of the period as the perimeter of a circle.
The Attempt at a Solution

The tension (resultant and tension for the hanging box) was calculated using the weight of the hanging box.
Also, I'm in a Trig based physics course and we CAN'T do derivatives, actually we're not supposed to.
I have to find acceleration to calculate how long it takes the heavier box to reach the end of the table.
A small space probe of mass 235 kg is traveling at 85.0 m/s. It fires its main engine at an angle of 63.00 to its original direction of travel. The engine produces a thrust of 12,000 N and there is enough fuel on board for a 10.0 s burn. What distance will it have traveled...
It's a free fall problem and I have to calculate a = g
g = (2*(d-(vi * t)))/t^2
g = (2d)/t^2
The Attempt at a...
I've worked through it and at the 1st step I get:
How do they have
Do you switch the signs of an inequality when you take the inverse of both sides?
Im guessing that c = the distance between A and B.
a = the difference in time that the sound reaches the points
b = what I need to find?
I'm still unsure at how I'm reaching this conclusion, my book just says this is true and doesn't explain why.
Two recording devices are set 2400 feet apart, with the device at Point A to the west of the device at point B. At a point on a line between the devices, 400 feet from point B, a small amount of explosive is detonated. The recording devices record the time the sound...

sin (x) + sin (3x) + sin (5x) + sin (7x) = 4cos(x)cos(2x)sin(4x)

If I graph an equation with my ti 84, is there anyway I can take the x values in the 2nd [table] spreadsheet of of x and y values and make the x values fractions? They're all decimals and I wan't them in fractions if possible. Can it be done?
The rest of the class IS STRUGGLING, there were 2 high grades (92) and everyone else had below a 75. The mode was a 50%. The professor is incredibly hard, reads powerpoints made by the book's author. I asked her once to explain how the product to sum and sum to product identities were derived...
I got accepted into the University of Pittsburgh and the costs came to around 35K (15K Tuition, 9K Room and Board, 1K for fees, 6K for meal plan, 4K for books and personal and travel expenses). I got 20K but I still came short by 15K.
I'm currently working and studying hard in community...
