Question

The car starts at an initial position of So=0 with an initial speed of $V_o = 10 ft/s$ The speed rate of the car is given by the expression $V = 0.1 \sqrt{S} ft/s$ a. What is the best coordinate system to solve this problem in? b. When the car has traveled a distance of s=256 ft along a path, what is the radius of the curvature of the path at this instant? c. When the car has traveled a distance of s=441 ft along the path, what is the radius of the curvature of the path at that instant? d. How do you find the equation of the speed of the car as a function of s? e. What is the speed of the car at s=441 ft? f. What is the magnitude of the acceleration of the car when s=441 ft?

          The car starts at an initial position of
So=0 with an initial speed of $V_o = 10 ft/s$
The speed rate of the car is given by
the expression $V = 0.1 \sqrt{S} ft/s$
a. What is the best coordinate system to solve this problem in?
b. When the car has traveled a distance of s=256 ft along a path, what is
the radius of the curvature of the path at this instant?
c. When the car has traveled a distance of s=441 ft along the path, what
is the radius of the curvature of the path at that instant?
d. How do you find the equation of the speed of the car as a function of
s?
e. What is the speed of the car at s=441 ft?
f. What is the magnitude of the acceleration of the car when s=441 ft?

The car starts at an initial position of
So=0 with an initial speed of Vo = 10 ft/s
The speed rate of the car is given by
the expression V = 0.1 √(S) ft/s
a. What is the best coordinate system to solve this problem in?
b. When the car has traveled a distance of s=256 ft along a path, what is
the radius of the curvature of the path at this instant?
c. When the car has traveled a distance of s=441 ft along the path, what
is the radius of the curvature of the path at that instant?
d. How do you find the equation of the speed of the car as a function of
s?
e. What is the speed of the car at s=441 ft?
f. What is the magnitude of the acceleration of the car when s=441 ft?
