Chapter 9, Problem 31P

(a)

To determine

Whether the floor imparts the impulse to the person.

Introduction: Impulse is the physical quantity which changes the momentum of the body. When a force is exerted on a body for a short interval of time then the impulse is equal to the product of force and time interval.

(b)

To determine

Whether the floor do any work on the person.

Introduction: When the body is displaced in to the direction of applied force then work is said to be done.

(c)

To determine

The momentum of the person.

(d)

To determine

To explain: Whether the momentum comes from floor or not.

Introduction: The momentum is the product of mass and velocity and it is a vector quantity.

(e)

To determine

The kinetic energy of the person.

(f)

To determine

Whether the final kinetic energy comes from floor or not.

Introduction: The energy possessed by the body when it is in motion is known as kinetic energy.
