Step through a multi-concept dynamics problem involving forces, energy and motion
Problem
A 2.0 kg block slides down a frictionless ramp from a height of 1.5 m. It then collides with a stationary 3.0 kg block on a horizontal surface (μ = 0.2). How far does the second block slide before stopping?
Step 1: Find velocity at bottom of ramp using conservation of energy
Step 2: Use conservation of momentum for the collision
Step 3: Use work-energy theorem to find stopping distance
Click each step to reveal the solution. This integrates energy, momentum and forces.
