Question

two objects a and b of mass 10 kg and 50 kg respectively are moving with the same speed along a straight line which one would need a greater force to stop it and why

Answer 1

everyone will say that body B needs more force to stop. but body A needs more force to stop,because
MOMENTUM IN BODY A IS MORE THAN MOMENTUM IN BODY B.
Because mass is directly proportional to momentum

Answer 2

1)Object A need a greater force to stop it because the momentum in body A is greater than B because mass is directly proportional momentum so it need greater force to stop it because the masses of b object is 50 kg.
