Understanding Centripetal Force
Centripetal force is the force that keeps an object moving in a circular path. It always points towards the center of the circle.
Formula
The formula for centripetal force is:
* F = (mv^2) / r
Where:
* F is the centripetal force (in Newtons)
* m is the mass of the object (in kilograms)
* v is the velocity of the object (in meters per second)
* r is the radius of the circular path (in meters)
Calculations
1. Plug in the values:
* m = 2000 kg
* v = 25 m/s
* r = 80 m
2. Calculate the centripetal force:
* F = (2000 kg * (25 m/s)^2) / 80 m
* F = (2000 kg * 625 m^2/s^2) / 80 m
* F = 156250 N
Answer
The centripetal force on the car is 156,250 Newtons.
