A car is moving at a velocity of 75 m/s and comes to a complete stop

Mice21 [21]

Answer:

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 = $\frac{Final velocity - Initial velocity }{time}$

Insert parameters and solve,

Acceleration = $\frac{ 0- 75}{15}$ = -5m/s²

The acceleration of the car is -5m/s²
