excluding direction i.e., negative signs, the initial velocity is 8m/s and time taken is 16s
by using F=ma, the acceleration is found out to be 0.5m/s^2
then use v^2-u^2=2as to find out initial velocity by taking v=0 (sincde the body comes to rest)
at last, use v=u+at to find out time
you might get negative sings. but ignore them, since we are only considering magnitude
