Two physics questions?

Question

A car with a velocity of 27 m/s slows down at a rate of - 8.5 m/s2 to a stop in a distance
of 43 m on a dry road. The same car traveling at 27 m/s slows down at a rate of -6.5 m/s2 to a stop on a wet road.
a. How much farther does the car travel on the wet road before coming to a stop?
b. What maximum car speed will allow the car traveling on the wet road to stop in a distance of 43 m?


. A car traveling at 14 m/s encounters a patch of ice and takes 5.0 s to stop.
a. What is the car’s acceleration?
b. How far does it travel before stopping?

Answer 1

a.13 meters farther.

b. 23.6 m/s.


a. -2.8m/s^2.

b. 35 meters.

Answer 2

Yes, those are two physics questions.

For the next class, we will learn existentialist philosophy! ;)
