Rate of Change of Angular Momentum Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate of Change of Angular Momentum = (Moment of Inertia*(Final Angular Velocity-Initial Angular Velocity))/Time Duration
L_r = (I*(ω_f-ω_o))/t_rm
This formula uses 5 Variables

Variables Used

Rate of Change of Angular Momentum - (Measured in Newton Meter) - The Rate of Change of Angular Momentum is directly proportional to the external torque applied on the body.
Moment of Inertia - (Measured in Kilogram Square Meter) - Moment of Inertia is the measure of the resistance of a body to angular acceleration about a given axis.
Final Angular Velocity - (Measured in Radian per Second) - Final Angular Velocity of the particle.
Initial Angular Velocity - (Measured in Radian per Second) - Initial angular velocity is the velocity at which motion starts.
Time Duration - (Measured in Second) - Time Duration is what a clock reads, it is a scalar quantity.

STEP 1: Convert Input(s) to Base Unit

Moment of Inertia: 1.12 Kilogram Square Meter --> 1.12 Kilogram Square Meter No Conversion Required
Final Angular Velocity: 45.125 Radian per Second --> 45.125 Radian per Second No Conversion Required
Initial Angular Velocity: 14 Radian per Second --> 14 Radian per Second No Conversion Required
Time Duration: 31 Second --> 31 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_r = (I*(ω_f-ω_o))/t_rm --> (1.12*(45.125-14))/31

Evaluating ... ...
