Question
You are coasting on your 14-kg bicycle at 18 m/s and a 4.5-g bug splatters on your helmet. The bug was initially moving at 1.5 m/s in the same direction as you. If your mass is 70 kg, answer the following questions:
- What is the initial momentum of you plus your bicycle?
pi=pi= Correct kg m/s - What is the initial momentum of the bug?
pi=pi= Correct kg m/s - What is your change in velocity due to the collision the bug? Mind the sign of your answer; to enter your answer in scientific notation, use the "E notation" (to enter 3.14×10−53.14×10-5, enter "3.14E-5").
Δv=Δv= Incorrect m/s - What would the change in velocity have been if the bug were traveling in the opposite direction? Mind the sign of your answer; to enter your answer in scientific notation, use the "E notation" (to enter 3.14×10−53.14×10-5, enter "3.14E-5").
