Problem

A car travelling in a straight line reduces its speed uniformly while approaching a traffic signal. a. (a) The speed of the car falls from 25 m/s25\,\text{m/s} to 5 m/s5\,\text{m/s} while it travels 60 m60\,\text{m}. Calculate the time taken for this part of the journey. b. (b) Using your answer from part (a), find the magnitude of the car’s acceleration during this interval.
