Homework Statement
Approaching one of the many sharp horizontal turns in the Monaco Grand Prix, an experienced Formula-1 driver slows down from 135 km/h to 55 km/h while rounding the bend in 10 s. If the driver continues to decelerate at this same rate and the radius of the curve is 15 m, what is the acceleration of the car the moment that its speed reaches 55 km/h?
Homework Equations
I think we're probably going to need these 2:
[itex] V_{0x} = a_x t = V_x[/itex]
[itex]\Delta x = (1/2)(V_x + V_{0x})t [/itex]
The Attempt at a Solution
Well before I can start this problem I already have a bunch of question. I would like the members of this board to help me with this only, as to not do the problem for me because I won't learn if that happens.
So let me see if I understand the question correctly:
Before reaching the turn, the driver decides to slow down. While traveling with the curve, he is slowing down at the same time from 135 km/h to 55 km/h. and it takes him 10 seconds to slow down to 55 km/h?
Do I have that right? Or does he slow down to 55 km/h before hitting the curve, and while going through the curve he is at a constant 55 km/h the whole time?
You're given radius = 15 m, using 15 m * pi you get the distance from where the curve starts to where it ends, 47 m, am I correct here?
