SUMMARY
The magnitude of the impulse on the wall from a ball with a mass of 150 g, striking at a speed of 5.2 m/s and rebounding with 50% of its initial kinetic energy, is calculated to be 1.3 N·s. The impulse (I) is derived from the change in momentum (ΔP), which is influenced by the initial and final kinetic energies. The initial kinetic energy (KE) is determined using the formula KE = 1/2 m v^2, leading to the necessary calculations for impulse.
