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 the car? a. 15,625 n b. 703 n c. 20,250 n d. 625 n

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

Which is not an example of how an object gains elastic potential energy by stretching? a. jumping on a pogo stick b. pulling on a rubber band c. jumping on a trampoline

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
