They left Maria’s house with an initial velocity of 11 m/s and reached the freeway at a velocity of 130 m/s in 7 minutes. What is their acceleration

Final answer:

The acceleration of the object as it traveled from Maria's house to the freeway is approximately 0.283 m/s², calculated using the change in velocity and time.

Step-by-step explanation:

The student's question about the change in velocity from Maria's house to the freeway involves calculating acceleration. To find the acceleration, we use the equation:

a = ∆v / ∆t

Where ∆v is the change in velocity and ∆t is the change in time. Here, ∆v = vf - vi = 130 m/s - 11 m/s = 119 m/s. The time ∆t must be converted to seconds, so 7 minutes times 60 seconds/minute gives 420 seconds.

Now plug these values into the equation:

a = 119 m/s / 420 s ≈ 0.283 m/s²

Therefore, the acceleration is approximately 0.283 m/s².
