(chatquestion)...What is the average speed of the particle over the Intervals in (a) and a 2 The velocity-time graph of a particle in one-dimensional motion is sho Fig. 3.29: 3.28 Consider the po where coordinates Suppose now that de decrease and appeach m to the line PQ as dg-0, u0. You cn polnt P as shown in Pg, 3.30s Ths m P. denoted by m t2 m Im Fig. 3.29 The limit of the ratio by/x as Ax au Which of the following formulae are correct for describing the motion of the particle over the time-interval t and is written as dy/dx t.
