Answer:
D. 6 m/s²
Explanation:
Given parameters:
Initial velocity = 36m/s
Final velocity = 0m/s
Time taken = 6s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time;
Mathematically;
Acceleration =
v is the final velocity
u is the initial velocity
t is the time
Acceleration = = -6m/s
The acceleration of the car must have been 6m/s²
