Answer:
Georgia is now running at the speed of 10 m/s. The equation to be used is the first equation of rectilinear motion which is v=u+at.
Step-by-step explanation:
This problem is a rectilinear motion problem. Let us first list all the given values so that we can see what equation we'll going to use to solve it.
Initial velocity = 4 m/s
Acceleration = 2 m/s^2s
2
Time = 3 s
There are 3 equations of rectilinear motion. These 3 are listed below:
v = u + at
Δs = ut + \frac{1}{2}
2
1
at^2t
2
v^2 = u^2 + 2av
2
=u
2
+2a Δs
where u = initial velocity, v = final velocity, a = acceleration, Δs = distance traveled, and t = time.
With the given information we can now decide what equation to use. We will use the first equation.
Solving mathematically:
v = u + at
v = 4 m/s + (2 m/s^2s
2
)(3 s)
v = 10 m/s
Final answer is 10 m/s.
