A particle, moving in a straight line with speed 5U m s−15U\text{ m s}^{-1}5U 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 16 seconds before decelerating uniformly to rest in a further 2 seconds.
sketch a velocity-time graph for this information.
find an expression for each of the decelerations in terms of UUU.
Given U=4U=4U=4, find the total distance travelled by the particle.
