4. A 905 kg car travels around a circular track with a circumference of 3.25 km. If the magnitude of the centripetal force is 2140 N, what is the car's tangential speed?

Question

Answer 1

To find the car's tangential speed, we can use the formula for centripetal force:

where:-

is the centripetal force,-

is the mass of the car,-

is the tangential speed, and-

is the radius of the circular track.Given:-

N,-

kg, and-

(since the circumference is

).First, let's calculate the radius

:

Now, we can rearrange the centripetal force formula to solve for the tangential speed

:

Plugging in the values:

Therefore, the car's tangential speed is approximately 11.1 m/s.
