A car traveling initially at 7.41 m/s accelerates at the rate of 0.752 m/s
2
for 2.74 s.
What is its velocity at the end of the acceleration?
Answer in units of m/s
vf= vi+at
45
To find the velocity of the car at the end of the acceleration, we can use the formula for velocity:
v = u + at
where:
v = final velocity
u = initial velocity
a = acceleration
t = time
Given:
Initial velocity, u = 7.41 m/s
Acceleration, a = 0.752 m/s^2
Time, t = 2.74 s
Let's substitute the given values into the formula:
v = 7.41 m/s + (0.752 m/s^2) * 2.74 s
Now, we can solve this equation to find the final velocity:
v = 7.41 m/s + 2.03448 m/s
v = 9.44448 m/s
Therefore, the velocity of the car at the end of the acceleration is 9.44448 m/s.
