2 The graph of the position s of a point of a milling machine as a function of time is a straight linc. 2 s) s = 90 fIllIl. 2 S, the di~placement of the point is 111'> = - 180 mm. (a) Detennine the equation for s as a function of time. (b) What is the velocity of the point? 3 The graph of the velocity 11 of a point as a function of time is a straight line. s. eaJ Detennine the acceleration of the point by calculating the slope of the straight line. (b) Obtain the equation for v as a function of time and use it to detcnnine the acceleration of the point.

Ds= '" v(s) l''0 dt The next two examples show how you can analyse the motion of an object when its acceleration is a fanction of velocity or position. 1. 1. Dctcnnining the velocity when you know the acceleration as a function of velocity or position. If you know a - a(v): Separate variables, dv dt - a(v) dv -=dt a(o) or apply the chain rule, dv d1)ds dv . -=--=-v_a(v) dt ds dt ds then separate vaIiables, vdv --=ds a(v) If you know a - a(s): Apply the chain rule, dv dvds dt = J;di dv ·······v ds then separate variables!

10). 4). 7(a)). 7(b)). :eleration and velocity of P and changes in its velocity and position, You can often use these relationships to obtain a qualitative understanding of an object's motion, and]lin some cases you can even use them to determine its motIOn. il , In some situations, lithe acceleration of an object is constant, or nearly constant. For example, if you drop a dense object such as a golf ball or rock and it doesn't fall too fh, you can neglect aerodynamic drag and asstune that its acceleration is equalll to the acceleration of gravity at sea level.
