My formula for B is correct, i tested it out on graph paper. I got: -40cos37it - 46.1jt + 2.5i + 4j To summarize, after one hour (since the velocities are in km/h), relative to ship B, ship A is (-40cos37+2.5) units West of ship B, and (-46.1+4) units south of ship B.

Ok, I got a and b, and now I am stuck on C. How do I find the time when the separation of the ships is the least?

Homework Statement -Ship A is located 4 km north and 2.5 km east of ship B -ship A has a velocity of 22km/h south -ship B has a velocity of 40km/h in a direction 37 degrees north of east a) Find the velocity of A relative to B in unit vector notation, with i towards the east b) Write...

I think I figured it out...I can use the normal vector of the plane as my direction vector.

Homework Statement Find the Vector eqn of a line which passes through P(2, -1, 3) and is perpendicular to the plane 3x -2y -z =0. Homework Equations Line(x) = P + td where d is a direction vector The Attempt at a Solution My main problem here is trying to find the direction vector for the...

Homework Statement 1000m^2 garden. 3 sides made of wooden fence. 1 side made of vinyl(costs 5x as much as wood). Length cannot be more than 30% greater than the width. Find the dimensions for the minimum cost of the fence. Homework Equations 1000 = LW C = 2L + W + 5W The...

Honestly, I believe in intelligent design. Where did the particles that made the big bang come from? Where did the law of gravity come from? How did it come to be? Too many questions, too many unknowns, too many coincidences imo for it to be the result of a random explosion. This universe...

Personally, I don't believe in the big bang. But those who do, can you explain this to me please. We all know that the Earth is exactly the right mass to orbit the sun, and that the inertia of the Earth keeps it from flying into the sun. We also know that the velocity of the Earth is exactly...

Hey guys, what's up. I live in Canada and am currently in high school. However, next year I believe I will be going to university for engineering. I am interested in civil, however, I'm not sure if I should rush off right to Waterloo without taking a year of general first year engineering...
