a) Consider a particle moving at a constant speed in a straight line with no forces acting on it. For an arbitrary observer located at a xed point O, show mathematically that an imaginary line joining the observer to the particle sweeps out equal areas in equal time intervals. b) Consider now instead a particle following a circular trajectory with constant angular velocity and an observer at the centre of the circle. Show that the imaginary line that joins the observer to the particle sweeps out equal areas in equal times.

A particle P of mass 2m can slide along a smooth rigid straight wire. The wire has one ofits points fixed at the origin ’O’, and is made to rotate in a plane through ’O’ with constantangular speed Ω. Show that r , the distance of P from O, satisfies the equation r ̈ − (Ω^2)*r = 0 Initially, P is at rest (relative to the wire) at a distance a from O. Find r as a function of t in the subsequent motion.

Quite apart from effects due to Earth’s rotational and orbital motions, a laboratory reference frame is not strictly an inertial frame because a particle at rest there will not, in general, remain at rest; it will fall. Often, however, events happen so quickly that we can ignore the gravitational acceleration and treat the frame as inertial. Consider, for example, an electron of speed v =0.992c, projected horizontally into a laboratory test chamber and moving through a distance of 20 cm. (a) How long would that take, and (b) how far would the electron fall during this interval? (c) What can you conclude about the suitability of the laboratory as an inertial frame in this case?
