The automobile is originally at rest s = 0. if it then starts to increase its speed at ft/s2, where tis in seconds, determine the magnitudes of its velocity and acceleration at s= 550 ft.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
