Centripetal force = mass * centripetal acceleration
F(c)=m*v^2/R
640=1500(13.4)^2/R
R=420.84m
The radius of the curve is 421m.
What is centripetal force ?
"A force that acts on a body moving in a circular path and directed towards the centre around which the body is moving is called Centripetal force. When an object travels around a circular path with a constant speed, it experiences an accelerating centripetal force towards the centre."
What is acceleration ?
"Acceleration refers to increasing speed, decreasing speed, or changing direction. To determine the acceleration of an object, you must calculate its change in velocity per unit of time."
