Acar of mass 1500 kg drives in a circle with a constant speed of 18 m/s. what is the radius of the circle if the centripetal force on the car is 3313.6 n?

146.7 m

Explanation:

Given mass of the car, m = 1500 kg

speed of the car, v = 18 m/s

Centripetal force on the car, F = 3313.6 N

As car moves in circular motion, so the centripetal force on the car is given by

Here, r is the radius of circle.

Substituting the given values in above formula, we get

      r = 146.7 m

Thus, the radius of the circle is 146.7 m.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

real, smaller and upside-down.   so the answer should be b.
