A particle undergoes uniform circular motion. This means that it moves in a circle of radius R about the origin at a constant speed. The position vector of this motion can be written Here, analogous to the simple harmonic motion problem of HW 1, ω is the angular frequency and has units of rad/s 1/s and can also be written in terms of the period of the motion as 2π (a) Show that the particle resides a distance R away...

A car is speeding up uniformly at a rate of 0.400 m/s2 while traveling counterclockwise around a circular track of radius 500 m. At the instant the car is moving due north, its speed is 9.00 m/s. What is the magnitude (in m/s2) and direction (in degrees west of north) of the total acceleration of the car at this instant? Use a positive angle for west of north and a negative angle for east of north.
