Question
a car (m=2,000kg) has an initial speed of 25m/s and the driver applies the brakes over a distance of 150 meters until the car comes to a stop, what is the average force required to stop the car over the 150m? a car (m=2,000kg) has an initial speed of 25m/s and the driver applies the brakes over a distance of 150 meters until the car comes to a stop, what is the average force required to stop the car over the 150m? a car (m=2,000kg) has an initial speed of 25m/s and the driver applies the brakes over a distance of 150 meters until the car comes to a stop, what is the average force required to stop the car over the 150m?Explanation / Answer
V2=2*a*s
a=625/150 =4.1667 m/s2
F=m*a = 2000x4.1667= 8333.33 N
