A 70 kg Throckmorton was riding his skateboard when a small, but juicy 0.001 kg beetle hits the front of his helmet, splattering, obstructing his view. Who experienced the greatest change in momentum?

Momentum before = momentum after

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(70.0 kg) (3.0 m/s) + (2.0 kg) (3.0 m/s) = (70.0 kg) (3.1 m/s) + (2.0 kg) v

210 kg m/s + 6 kg m/s = 217 kg m/s + (2.0 kg) v

-1 kg m/s = (2.0 kg) v

v = -0.5 m/s

The skateboard's velocity is 0.5 m/s west. Hope I helped and have a good day!

前の勢い=後の勢い

m₁u₁+m₂u₂=m₁v₁+m₂v₂

（70.0 kg）（3.0 m / s）+（2.0 kg）（3.0 m / s）=（70.0 kg）（3.1 m / s）+（2.0 kg）v

210 kg m / s + 6 kg m / s = 217 kg m / s +（2.0 kg）v

-1 kg m / s =（2.0 kg）v

v = -0.5 m / s

スケートボードの速度は西に0.5m / sです。私が助けて、良い一日を過ごせることを願っています！

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
