# Mechanics Question. HELP!! watch

1. Stuck on a question for an A level CIE Past Paper. 9702/23/O/N/13.
b) A car of mass 1500 kg travels along a straight horizontal road. The variation with time t of the displacement x of the car is shown in Fig. 3.1.

ii) Calculate the average velocity during the time interval t = 0 to t = 1.5s

iii) Show that the average acceleration between t = 1.5s and t = 4.0s is -7.2ms^-2

I suspect that Figure 3.1 is important when it comes to answering this question please could you post a photo of it?

And what have you tried so far?
it's okay, i figured it out, but thanks either way.
