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.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
