SUMMARY
A 0.500 kg ball attached to a 70 cm cord strikes a stationary 2.5 kg block in a perfectly elastic collision. The initial potential energy of the ball is calculated to be 3.43 J, leading to a kinetic energy of 2.62 J just before impact. Using conservation of momentum and energy equations, the final velocities are determined to be -1.75 m/s for the ball and 0.87 m/s for the block after the collision. The discussion highlights the importance of understanding elastic collision principles and energy conservation in physics.
