Answer:
28.1 mph
Explanation:
The force of friction acting on the car provides the centripetal force that keeps the car in circular motion around the curve, so we can write:
(1)
where
is the coefficient of friction
m is the mass of the car
g = 9.8 m/s^2 is the acceleration due to gravity
v is the maximum speed of the car
r is the radius of the trajectory
On the snowy day,
So the radius of the curve is
Now we can use this value and re-arrange again the eq. (1) to find the maximum speed of the car on a sunny day, when . We find:
If the velocity is constant, then the position/time graph has a constant slope, meaning a straight line.
The slope may be any constant value ... positive, negative, or zero.
-∞ < slope < +∞
Answer:
Found this off of google, "The first model which is known as "Thomson atomic model" of the atom that showed the structure of the inside of an atom is developed by William Thomson."
Hope this helps, have a great day/night and stay safe! :) :D :3
Answer:
