The car, traveling at a speed of 190 km / h, began to brake evenly and after 10 seconds dropped the speed to 30 km / h. What is the acceleration of a car?
Consider a car-related system. At first, the car moved uniformly, but then, it is said, it began to brake with the same acceleration, therefore, equally slow. Then
V1 = V0-a * t
a * t = V0-V1
a = (V0-V1) / t = 16m / s ^ 2
