A car changes its velocity from 25m/s to 15m/s in 45. Find the acceleration

To find the acceleration, we can use the formula:

acceleration = (final velocity - initial velocity) / time

In this case, the car changes its velocity from 25 m/s to 15 m/s, so

initial velocity = 25 m/s
final velocity = 15 m/s

The time taken for this change is given as 45 s.

acceleration = (15 m/s - 25 m/s) / 45 s

Simplifying this expression, we have:

acceleration = -10 m/s / 45 s

Therefore, the acceleration of the car is approximately -0.222 m/s².
