Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

A firework explodes into three pieces as shown in the diagram below. Now that you have set up the equation for the x and y components of the final momentum of the firework, let's do some physics! Given: The initial firework had a mass of 9.0 kg and was launched at vi = 110 m/s vertically straight up. The firework explodes into three pieces of equal mass 3.0 kg. The angles θ1 = θ3 = 20 ∘. Speed v1 = 100 m/s. What is the speed v2? Note: the angles shown for mass m1 and mass m3 are relative to the horizontal x axis. Mass m2 is moving straight up (y axis).
