Answer :
Final answer:
The magnitude of the car's acceleration while braking is 50 / t, where t is the time taken to stop the car.
Explanation:
In order to calculate the acceleration of the car while it was braking, we can use the formula:
Acceleration = (Final Velocity - Initial Velocity) / Time
Since the car came to a stop, the final velocity is 0 km/hr. The initial velocity is given as 50 km/hr. We need to convert the distance traveled into meters, so the distance is 35 m.
Plugging in the values, we find:
Acceleration = (0 - 50) / t = -50 / t
So the magnitude of the car's acceleration while braking is 50 / t, where t is the time taken to stop the car.
