Problem 5

A surveying team records the following displacement vectors on three days (24 hour days) of walking, each one in succession (1, then 2, then 3) (Give 2 significant figures):

d​1 ​= (7 ​i ​+ 8 ​j​)km, ​d​2 ​= (6 ​i ​+ 2 ​j​)km, and ​d​3 ​= (2 ​i ​+ 9 ​j​)km.
(a)​: Sketch these vectors on a Cartesian plane. ​Hint: ​The vectors should all be connected

head-to-tail.

(b)​:Write the total displacement vector​ d(​total) f​or the three days in Cartesian and polar coordinates give your answer in meters. Your answer should look similar to the three dis- placement vectors given above.

(c)​: Assuming the members of the team could continuously survey for a full 5 days without sleeping, determine the average velocity vector of the team throughout the first three days in Cartesian coordinates. Answer in m/s.

(d)​: If the team were to continue to move in the direction of the total displacement vector at the same average velocity as the first 3 days, what would be the final displacement vector after a full 5 days of surveying?

The three following coordinate vectors are given in unitary coordinates (in [m]): a = (5; 0; 0) b = (-1; 4; 1) c = (0; 1; 3) a) Determine the new coordinate system, giving |a|, |b|, |c|, alpha, beta and gamma. Use vector operations to obtain the values. b) Determine the metric matrix for this coordinate system, and the volume of the parallelepiped spanned by a, b, c. For the volume calculation, use the determinant of the metric matrix. c)...

Your task will be to derive the equations describing the velocity and acceleration in a polar coordinate system and a rotating polar vector basis for an object in general 2D motion starting from a general position vector. Then use these expressions to simplify to the case of non-uniform circular motion, and finally uniform circular motion. Here's the time-dependent position vector in a Cartesian coordinate system with a Cartesian vector basis: ⃗r(t)=x (t) ̂ i+y(t) ̂ j where x(t) and y(t)...
