Answer:
-8m
Step-by-step explanation:
This question only requires to to substitute t = 0 and t = 1 into the equation to find the displacement.
Lets find the displacement at t = 0.
[tex]x(0)=4sin(\pi (0)+\frac{\pi }{2} )\\=4sin(\frac{\pi }{2} )\\= 4m[/tex]
Lets find the displacement at t = 1.
[tex]x(1) = 4sin(\pi (1)+\frac{\pi }{2} )\\=4sin(\pi +\frac{\pi }{2} )\\=-4m[/tex]
Total displacement = Final Position - Initial Position
= x(1)-x(0)
= -4m - 4m
= -8m
