Solve the given parts of following problem:
Problem: The driver of a 1720kg car traveling on a horizontal road at 102km/h suddenly applies the brakes. Due to a slippery pavement, the friction of the road on the tires of the car, which is what slows down the car, is 30.0% of the weight of the car.
Part A: What is the acceleration of the car? Give your answer as the magnitude of the acceleration.
Part B: How many meters does it travel before stopping under these conditions?
I need help to find how many meters does it travel before stopping under these conditions.
