A car is driving around a curve of radius 100 m. The driver presses on the gas pedal and accelerates the car at a constant rate of 3 m/s2 . What is the total acceleration of the car if its speed is 22 m/s?

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?
