1.	7. A 4 kg mass moving with speed 2 m/s, and a 2 kg mass moving with a speed of 4 m/s, are gliding over ahorizontal frictionless surface. Both objects encounter the same horizontal force, which directly opposes theirmotion, and are brought to rest by it. Which statement best describes their respective stopping distances?(1) The 4 kg mass travels twice as far as the 2 kg mass before stopping12) The 2 kg mass travels twice as far as the 4 kg mass before stopping(3) Both masses travel the same distance before stopping(4) The 2 kg mass travels greater than twice as far
Answer» Answer: OPTION 2 is CORRECT as the speed 2KG mass is TWICE than 4kg mass
