an automobile traveling at 25.0 km/h along straight,level road accelerates to 65.0 km/h in 6.00s what is the acceleration

acceration=(vfinal-vinitial)/timetoaccelerate.

Now most would change the velocity to m/s, but it is not necessary.

To find the acceleration of the automobile, we can use the acceleration formula:

acceleration = (final velocity - initial velocity) / time

Initial velocity (u) = 25.0 km/h
Final velocity (v) = 65.0 km/h
Time (t) = 6.00 seconds

First, we need to convert the velocities from km/h to m/s, as the SI unit for acceleration is m/s².

1 km/h = 0.2778 m/s

So, the initial velocity (u) becomes:
u = 25.0 km/h * 0.2778 m/s/km/h = 6.95 m/s

The final velocity (v) becomes:
v = 65.0 km/h * 0.2778 m/s/km/h = 18.06 m/s

Now we can substitute the values into the acceleration formula:

acceleration = (v - u) / t
acceleration = (18.06 m/s - 6.95 m/s) / 6.00 s
acceleration = 11.11 m/s / 6.00 s
acceleration = 1.85 m/s²

Therefore, the acceleration of the automobile is 1.85 m/s².
