Question

An object with a mass of 5.00 g is moving to the right at 14.0 cm/s when it is overtaken by an object with a mass of 26.0 g moving in the same direction with a speed of 19.0 cm/s. If the collision is elastic, determine the speed of An object with a mass of 5.00 g is moving to the right at 14.0 cm/s when it is overtaken by an object with a mass of 26.0 g moving in the same direction with a speed of 19.0 cm/s. If the collision is elastic, determine the speed of each object after the collision in centimeters per second. 26.0 g object cm/s 5.00 g object cm/s

Answer 1

Given og glumis 19cmls. 1. Let the mass of sy be my and its initial velocity be ", = memps. Let the mass of 269 be me and its initial velocity be "g = 180m/s In any collifion, momentum is comserved. minit m2 42 = muitmals. - where; Nen ve are final velocities after collisions of mi, my respectively. since the collision is elastic, the binetic enersies are also conserve do
