Question

i give medals!
A car 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?

Answer 1

F = m v^2 / r know F, m, v, solve for r

Answer 2

so its set up 3313.6=1500(18^2)/r?
how would i make it sat r=? @douglaswinslowcooper

Answer 3

say*

Answer 4

yes

r = m v^2 / F

Answer 5

Seems you got it.

Answer 6

i got 146.67
& im pretty sure its correct.
thanks c: @douglaswinslowcooper

Answer 7

That's what I got, too. Well done.
