A salad spinner is moving CCW at constant angular velocity. It travels a full circle in 2.00s.

a) Calculate its angular velocity, its period and its frequency.

b) You start your stopwatch when θ = 0. Complete the table:

Time 0 0.25 0.50 0.75 1.00 1.250 1.500 1.75 2.00 3.00 4.00
Angle (rad) 0

Time as a fraction of T

0 T/2 T

c) Draw the angle and the time as a fraction of the period on a unit circle.

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)...
