Question

7. A 905 kg test car travels around a 3.25 km circular track. If the magnitude of the centripetal force is 2140 N. what
is the car's speed?​

Answer 1

Answer:

Your speed will be 35m/s.

Explanation:

the total circular track is the circumference so we can find the radius by using formula :

             circumference = 2 π r

put value of circumference into its correct position and you'll have the radius of track, then use formula for centripetal force and you'll have your answer.
