Answer:
The car has an acceleration of -5m/s² or a deceleration of 5m/s²
Explanation:
Given parameters:
Initial velocity = 75m/s
Final velocity = 0m/s
Time taken = 15s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time.
Mathematically;
Acceleration = [tex]\frac{Final veloclty - Initial velocity }{Time}[/tex]
Insert parameters and solve;
Acceleration = [tex]\frac{0 - 75}{15}[/tex] = -5m/s²
The car has an acceleration of -5m/s² or a deceleration of 5m/s²
