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！
