Web0 = (20m/s)^2 + 2*acceleration*40m. -400 = 80a. a = -5 m/s^2. The acceleration is negative! Don't worry, this only means that the car is slowing down, which is quite logical since you are stepping on the brakes. Back to Newton's second law, we have. F = ma. F = 1000kg * 5 m/s^2 = 5000N. Thus, the average braking force of the car is 5000N. WebNov 28, 2024 · 2. Acceleration, deceleration, velocity-time graph interpretation, calculations and problem solving.
