A car traveling at +6.3 m/s accelerates at the
rate of 0.65 m/s^2
for an interval of 2.2 s.
Find vf .
Answer in units of m/s
To find the final velocity (vf), we can use the equation:
vf = vi + at
Where:
vf = final velocity
vi = initial velocity
a = acceleration
t = time
Given:
vi = +6.3 m/s (positive because it states the car is traveling at +6.3 m/s)
a = 0.65 m/s^2
t = 2.2 s
Substituting the values into the equation, we have:
vf = 6.3 m/s + (0.65 m/s^2)(2.2 s)
Now, let's calculate the final velocity:
vf = 6.3 m/s + (0.65 m/s^2)(2.2 s)
= 6.3 m/s + 1.43 m/s
= 7.73 m/s
Therefore, the final velocity (vf) is 7.73 m/s.
