Vin diesel is filming yet another  fast and furious  movie. he is driving a 1200kg sports car around a circular track of 1.25km. if the magnitude of the centripetal force is 2600n, what is the car’s tangential speed?

20.73 m/s

Explanation:

The centripetal force is given by the following equation:

(1)

Where:

is the centripetal force

is the mass of the car

is the centripetal acceleration

Isolating :

(2)

(3)

(4)

Now, there is a relation between the centripetal acceleration and the tangential velocity:

(5)

Where is the tangential velocity and is the radius of the circular path, which can be found if we know its length :

(6)

(7)

(8)

(9)

Substituting (4) and (8) in (5)

(5)

Finding :

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
