To find the final position of the object after 2 seconds, we can plug in the given values into the equation of motion:
x = x0 + v0t + (1/2)at^2
Given:
x0 = 2 m
v0 = 4.5 m/s
a = 0 (no acceleration)
t = 2 s
Plugging in these values, we get:
x = 2 + 4.5(2) + (1/2)(0)(2^2)
x = 2 + 9 + 0
x = 11
Therefore, the final position of the object after 2 seconds is 11 m. So the correct option is:
11 m
