What is the final velocity?
V1=18m/s
a=-4 m/s2
(add it in even though I left it out)
t=2
Find v2=?
v2=v1+ATriangleT
v2=18m/s+(-4m/s2) (1.5s)
v2=18m/s+(-6m/s)
v2=12m/s
correct.
So the final velocity is?
A. 10m/s
B. 12m/s
C. 13m/s
D. 14m/s
To find the final velocity (v2), we can use the equation v2 = v1 + at, where v1 is the initial velocity, a is the acceleration, and t is the time.
In this case, you have the initial velocity, v1, given as 18 m/s and the acceleration, a, given as -4 m/s^2 (negative because it's deceleration).
The time, t, is given as 2 seconds.
To find v2, substitute the values into the equation:
v2 = v1 + at
= 18 m/s + (-4 m/s^2)(2 s)
= 18 m/s + (-8 m/s)
= 10 m/s
Therefore, the final velocity (v2) is 10 m/s.
