An object is pushed from rest across a sheet of ice, accelerating at 5.0 m/s2 over a distance of 80 cm. The object then slides at a constant speed for 4.0 s until it reaches the rough section that causes the object to stop in 2.5 s.
a) What is the speed of the object when it reaches the rough section?
b) At what rate does it slow down once it reaches the rough section?
c) What is the total distance that the object slides?
Any help will be appreciated.
The Attempt at a Solution
a) find v
b) find a
c) find d(distance)
I have some answers but I don't think its correct because of the rough section part of the question.
