Acar with a mass of 2,000 kilograms is moving around a circular curve at a uniform velocity of 25 meters per second. the curve has a radius of 80 meters what is the centripetal force on a car

area of focus

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
