You are coasting on your 10-kg bicycle at 15 m/s and a 8.0-g bug splatters on your helmet. The bug was initially moving at 4.0 m/s in the same direction as you. If your mass is 70 kg, (a) what is the initial momentum of you plus your bicycle? (b) What is the initial momentum of the bug? (c)What is your change in velocity due to the collision with the bug? (d) What would the change in velocity have been if the bug were traveling in the opposite direction?
