5x + 3 = 12
take the 3 to the other side
5x = 12 - 3 = 9
5x = 9
divide both sides by 5
x = 9/5
x = 1.8
It should be noted that the angular momentum remain constant and kinetic energy of the skater increases.
<h3>What is Angular momentum?</h3>
Angular momentum can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then angular momentum is constant.
Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.
