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?
a = (V-Vo)/t = 25-0) / 4 = 6.25 m/s^2.
a car moving at speed of 5 m/s, acceleration at a constant rate of 2.50 m/s^2 for 5.00 s. what is the car's final speed?
what is the awnser
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 because the car starts from rest. The final velocity is 25 m/s, and the time taken is 4.0 seconds.
Now let's substitute the values into the formula:
acceleration = (25 m/s - 0 m/s) / 4.0 s
acceleration = 25 m/s / 4.0 s
Simplifying the expression:
acceleration = 6.25 m/s²
Therefore, the acceleration of the sedan is 6.25 m/s².
