Question

Part1: you are driving at the speed of 34.7 m/s (77.6383 mph) when suddenly the car in front of you ( previously

driving at the same speed) brakes and begins to slow down with the largest deceleration possible without skidding. Considering an average human reaction you press your brake 0.571 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.71 between both cars' wheels on the road. The acceleration of gravity is 9.8 m/s^2. Calculate the acceleration of the car in front of you when it brakes. Answer in units of m/s^2.

part 2: calculate the braking distance for the car in front of you. Answer in units of m.

Part 1 ;
4 = 34. 7 mls
= Omls
We
know that
Ff = Mmg = Fa
. . Mig = ma
Hence a = Mg
where u= Coefficient of state friction
between both cars' wheels on
a = 9 8 x 0. 71
the road.
6. 958 mls
Part 2 ;...
