A particle, moving in a straight line with speed 6U m s−16U\text{ m s}^{-1}6U m s−1, decelerates uniformly for 6 seconds, which reduces its speed to 2U m s−12U\text{ m s}^{-1}2U m s−1. It maintains this speed for a further 8 seconds before decelerating uniformly to rest in a further 4 seconds.
sketch a velocity-time graph for this information.
find an expression for each of the decelerations in terms of UUU.
Given the total distance is 220 m, find the value of UUU.
