SUMMARY
The speed of a 100 g ball in Newton's Cradle, lifted to a height of 3.0 cm, can be calculated using the principles of energy conservation. The gravitational potential energy (Eg) at the height is 0.0294 J, derived from the equation Eg = mgh, where m = 0.1 kg and h = 0.03 m. This potential energy converts to kinetic energy (Ek) at the lowest point, represented by the equation Ek = 1/2 mv². By equating Eg and Ek, the final speed of the ball can be determined accurately.
