a foam boulder has a mass of 2kg and a velocity of 20m/s. a stone boulder has the same velocity (20m/s) but a mass of 20kg. which of the two has more momentum? Explain.
The definition of momentum, which you apparently need to review, will tell you the answer. Please do not waste your time and ours passing on such trivial questions to others.
Since momentum = M*V and they both have the same velocity (V), the more massive stone boulder has more momentum.
