Answer 1

Explanation:

• To find distance from velocity time graph,we will have to consider the area under graph..
• To find acceleration from V-T graph,we will have to find the slope of graph

to find the area from t=0s to t=18s, we will have to add the areas of ∆OAM+rectangle MABN+∆BNC+

∆BDC

i.e,. =(1/2×6×4)+(1/2×2×4)+(1/2×4×2)+(6×4)

=44m

And maximum acceleration means maximum slope(more steeper) it is in region OA

slope of OA=dY/dX=2/3=0.66 m/s^2

hope it helps you... thank you
