I'm having trouble with the third part to this question:
On a level road with its brakes on, the shortest distance in which a car traveling with 93 km/hr can stop is 91 m. This shortest distance occurs when the driver uses anti-lock brakes which means that that the car brakes without skidding.
The first part asks what the magnitude of the acceleration of the car is and I found that to be the absolute value of 3.67.
The second part asks what the coefficient between the tires and the pavement is and I found that to be 0.374 .
The third part then asks How steep a hill can the car park on, with the angle to the horizontal. I have no clue how to go about this. The only hint or help given on the online program is "Since the car stopped without skidding, the coefficient of friction you found in part (b) is actually the static coefficient of friction, which is the proper coefficient of friction for this part as well. "
How do I go about figuring this out with the information I have?
