SUMMARY
In the scenario involving Kevin skating before an inelastic collision with his brother, the conservation of momentum principle is essential for solving the problem. Kevin, with a mass of 84.2 kg, collides with his 23.2-kg brother and rolls off at a speed of 1.74 m/s. To find Kevin's speed before the collision, apply the momentum conservation equation: (mass of Kevin * initial speed of Kevin) = (combined mass * final speed after collision). This approach allows for the calculation of Kevin's initial speed prior to the collision.
