Answer :
Final answer:
The force of the collision between the car and the wall is -240,000 Newtons.
Explanation:
To calculate the force of a collision, we can use Newton's second law of motion which states that force equals mass multiplied by acceleration.
Given that the car goes from 40m/s to 0m/s in 0.5 seconds, we can calculate the acceleration using the equation:
acceleration = (final velocity - initial velocity) / time
acceleration = (0 - 40) / 0.5 = -80 m/s²
Now, let's calculate the force:
force = mass * acceleration
force = 3000 kg * -80 m/s² = -240,000 N
Therefore, the force of the collision between the car and the wall is -240,000 Newtons.
