(a) Consider a particle which starts moving around from the origin in a 3-dimensional space. De- termine the velocity vector v(t) in terms of φ and θ if it is constantly moving at the speed 5m/s, along the direction (φ,0). Here, φ denotes the angle between the z-axis and the projection of the position vector r(t) on the xy-plane; meanwhile θ denotes the angle between the z-axis and r(t). You may assume that (φ, θ) are fixed over time at...

Polar coordinates are used for planes. Extending this system into three dimensions in the simplest way results in a cylindrical coordinate system. A cylindrical coordinate system uses the same r and θ as in polar coordinates, with an added dimension along to the z-axis. The three coordinates that define a point in a cylindrical coordinate system is the triple (r, θ, z). Consider a point in the three-dimensional Cartesian coordinate system, (3, −4, 6) cm. Dacia and Katarina compute the...

Consider three elements from the vector space of real 2 times 2 matrices: |1> = [0 1 0 0] |2> = [0 1 0 1] |3> = [-2 -1 0 -2]. Are they linearly independent? Support your answer with details. (Notice we are calling these matrices vectors and using kits to represent them to emphasize their role as elements of a vector space.)
