A particle is revolving in a circular path of radius 7.3 m centered at the origin
9. A particle is revolving in a circular path of radius 7.3 m centered at the origin. Its speed increased uniformly from 93 m/s to 173 m/s in 2.5 seconds. Express its final net acceleration in terms of polar unit vectors.
10. A particle is revolving in a circular path of radius 8.2 m centered at the origin with a uniform acceleration. Its speed increases by 14.5 m/s every 3.2 seconds. By the time it passes point P on the circle its speed is 8.5 m/s. If the direction of the position vector of point P is 40 west of south, express the net acceleration at point P in terms of cartesian unit vectors.

A mechanical device consists of two circular gears, one of radius 2 centered at (0, -2) and the other radius 1 centered at (0, 1). The gear of radius 2 rotates clockwise at unit angular velocity (1 radian per second), while the gear of radius 1 rotates counterclockwise without slipping at the contact point. The two gears each carry a small peg on their circumference, and these pegs are connected together by an elastic band. Initially, both pegs are at...
