circular motion: could this happen?!?
1. Problem, given data
I have a car traveling a curve initially at 75 mi/hr. It comes to rest before it travels 350 ft along the curve. The radius of the curve is 650 ft.
I am asked if this situation is possible.
2. Equations
a = v^2/R
3. Attempt at a solution
a = v^2/R
v^2 = (a)(R)
= [(75mi/hr - 0mi/hr)(1m/s//2.24mi/hr)] [650ft(1 m / 3.28ft)]
when I find V, it's not the right answer.
This is not the correct answer. Am I setting this up correctly? Am i supposed to use s=r(angle) to determine the angle and transform this into a banking problem?
