Accelaration/deceleration is according to the formula:
#Deltav=axxt->a=Deltav//t#,
where #Deltav=#change in speed, #a=#acceleration, #t=#time

Explanation:

Fill in what we know:
#Deltav=-5.8m//s# (negative because of slowing down)
#t=0.059s#

So #a=(-5.8)/0.059~~-98.3m//s^2# (the #-# is for decelaration).

Note:
If you're familiar with the term #g#-force, this amounts to about #10xxg#, which only trained fighter pilots can stand (for a short time) without losing consciousness.
