Why does a moving object come to a stop on a frictional surface? a. the object’s kinetic energy is transformed into mainly heat energy. b. the object’s potential energy is transformed into mainly kinetic energy. c. the object loses all its energy in deformation. d. the object’s kinetic energy is transformed into mainly potential energy.

The correct answer to the question is - A) Object's kinetic energy is transformed into mainly heat energy.

EXPLANATION:

The friction is the opposing force which acts tangentially between two surfaces when there is a relative velocity between them.

As per the question, the moving object comes to rest after the application of frictional force.

Initially the object is in motion.Hence, the energy possessed by the moving object is kinetic energy.

When frictional force is applied on the moving object, the kinetic energy of the moving object will be converted into mainly heat energy. It is due to the fact that friction causes heat production between two surfaces in contact.

Hence, correct option will be that the object's kinetic energy is transformed into mainly heat energy.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
