Identical constant net forces act to push two identical masses A and B continuously from a starting line to a finish line. Mass A is initially at rest and mass B is initially moving toward the finish line. Both objects move the same distance while being pushed. 3) Which mass has the larger change in momentum? Explain your answer.
