A school teacher’s sedan can go from 0 to 25 m/s in only 4.0 seconds. What is the
acceleration of the sedan?
v=at
a=v/t=25/4=6,25 m/s²
6.25m/s^2
To find the acceleration of the sedan, we can use the formula:
acceleration = change in velocity / time
Given:
Initial velocity (u) = 0 m/s
Final velocity (v) = 25 m/s
Time (t) = 4.0 seconds
Substituting the values into the formula:
acceleration = (v - u) / t
acceleration = (25 m/s - 0 m/s) / 4.0 seconds
Simplifying the equation:
acceleration = 25 m/s / 4.0 seconds
acceleration = 6.25 m/s²
Therefore, the acceleration of the sedan is 6.25 m/s².
To find the acceleration of the sedan, we can use the formula:
acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity is 0 m/s since the sedan starts from rest. The final velocity is 25 m/s, and the time taken is 4.0 seconds.
Plugging these values into the formula:
acceleration = (25 m/s - 0 m/s) / 4.0 s
Simplifying:
acceleration = 25 m/s / 4.0 s
acceleration ≈ 6.25 m/s²
Therefore, the acceleration of the sedan is approximately 6.25 m/s².
