# Could you help me describe the motion below a-t graph (acceleration vs. time)?

How would you go about describing the motion of each slope? (*Assume [N] is +ve)

Step-wise explanation is as follows

- An object has acceleration
#a=0cms^-2# at time#t=0s# - We observe that its acceleration changes linearly to
#-2cms^-2# in the next#1s# . - For next
#1s# , from#t=1s " to " t=2s# , the acceleration increases linearly to#1cms^-2# . - From
#t=2s " to " t=5s# the object moves with constant acceleration of#1cms^-2# . - For next
#1s# , from#t=5s " to " t=6s# , the acceleration decreases linearly to#0cms^-2# - The object continues with
#0# acceleration for next#1s# , from#t=6s " to " t=7s# ,
