SUMMARY
The discussion focuses on calculating the final speed of a skateboarder at the bottom of a 6.2 m long ramp inclined at 13° with an initial speed of 2.1 m/s. Two primary methods are proposed for solving the problem: the conservation of energy approach, which equates the change in kinetic energy to the change in gravitational potential energy, and the force-acceleration method, which involves calculating the net force along the incline to determine acceleration and applying the third equation of motion. The initial velocity components were calculated as 2.05 m/s (x-component) and 0.47 m/s (y-component).
