Question

A thin rod of length d on a frictionless surface is pivoted about one end

Answer 1

The magnitude of the angular momentum of the rod immediately after the collision is given as (pf + pi) * d. (Option A).

What is Angular Momentum?

Angular Momentum may be defined or described as the vector quantity of the rotation of a body, which is arrived at by multiplying its moment of inertia by its angular velocity.

The formula for Angular Momentum is given as:

L = mvr; Where

L = Angular Momentum

m = mass

v = velocity; and

r = radius.

Answer 2

$\rm( P_f+P_i)d$ is the magnitude of the rod's angular momentum immediately after the contact. Option A is correct.

What is the definition of Angular Momentum?

Angular Momentum may be defined as the vector quantity of a body's rotation, which is calculated by multiplying its moment of inertia by its angular velocity.

The Angular Momentum formula is as follows:

$\rm L=I\omega$

$\rm L = mvr$

Where,

L is the angular momentum

m stands for mass.

v stands for velocity, and

r stands for radius.

Hence option A is correct.
