A particle performing a U.C.M. has a

The work done on a particle performing UCM is

A whistle revolves in a circle with an angular speed of 20 rad//sec using a string of length 50 cm . If the frequency of sound from the whistle is 385 Hz , then what is the minimum frequency heard by an observer which is far away from the centre in the same plane? v=340m//s

A particle starts moving at t = 0 in a circle of radius R = 2m with constant angular acceleration of a - 3 "rad/sec"^(2) . Initial angular speed of the particle is 1 rad/sec. At time t_(0) the angle between the acceleration vector and the velocity vector of the particle is 37^(@) . What is the value of t_(0) ?
