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 = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]
Insert parameters and solve,
Acceleration = [tex]\frac{ 0- 75}{15}[/tex] = -5m/s²
The acceleration of the car is -5m/s²
