Final answer:
The acceleration of a dog that goes from rest to 65 m/s in 5 seconds is 13 meters per second squared (13 m/s²).
Step-by-step explanation:
To calculate the acceleration of a dog that was at rest and then reached a speed of 65 m/s in 5 seconds, we can use the formula for acceleration, which is the change in velocity (Δv) divided by the change in time (Δt). The formula is: acceleration (a) = Δv / Δt.
Given that the initial velocity (vi) is 0 m/s (since the dog was at rest), the final velocity (vf) is 65 m/s, and the time (t) is 5 seconds, we can calculate the acceleration as follows:
Acceleration (a) = (vf − vi) / t
Acceleration (a) = (65 m/s − 0 m/s) / 5 s
Acceleration (a) = 13 m/s2
Therefore, the acceleration of the dog is 13 meters per second squared (13 m/s2).
