    Question 5c

    i've drawn a block on a flat surface with friction going left, normal reaction going up, 0.2g going down and acceleration going left(block comes to rest so it decelerates)

    i also know that s=2 u=4.2 v=0

    not sure what to do from here

    did i miss something out on my diagram?

    Use your variables you know to create a SUVAT equation to find the deceleration. Then use F=ma and that also F=\mu R
