A dragster and driver together have mass 929.4 kg. The dragster, starting from rest, attains a speed of 26.5 m/s in 0.55s. Find the average acceleration of the dragster during this time interval. Answer in units of m/s^2
a=v/t
To find the average acceleration of the dragster, we need to use the formula:
average acceleration = change in velocity / change in time
Given:
Initial velocity (u) = 0 m/s (starting from rest)
Final velocity (v) = 26.5 m/s
Time interval (t) = 0.55 s
To find the change in velocity, we subtract the initial velocity from the final velocity:
change in velocity = v - u
= 26.5 m/s - 0 m/s
= 26.5 m/s
Now, we can substitute the values into the formula:
average acceleration = change in velocity / change in time
= 26.5 m/s / 0.55 s
≈ 48.18 m/s^2
Therefore, the average acceleration of the dragster during this time interval is approximately 48.18 m/s^2.
