A car is moving at a velocity of 75 m/s and comes to a complete stop over 15 seconds. What is the cars acceleration?

The acceleration of the car is  -5m/s²

Explanation:

Given parameters:

Initial velocity  = 75m/s

Final velocity  = 0m/s

Time  = 15s

Unknown:

Acceleration of the car = ?

Solution:

Acceleration is the rate of change of velocity with time;

Mathematically;

      Acceleration =

Insert parameters and solve,

   Acceleration  =   = -5m/s²

The acceleration of the car is  -5m/s²

your answer would be “dry”
