Question

which has more Momentum between a metal sphere of mass 10 gram moving with a velocity of 400meter per second and a cricket ball of mass 400 grams thrown with a speed of 90km per hour

Answer 1

momentum of a metal sphere is less in comparison to a cricket ball because
momentum of metal sphere= mass × velocity so 10× 400 = 4000m/s
but
momentum of cricket ball= mass ×velocity so
25 × 400 = 10000m/s
so momentum of cricket ball is greater than momentum of metal sphere.
