CONSERVED MOMENTUM QUESTION?
When riding your bicycle one day, you notice a toddler standing in the street in the path of a speeding car. Still on your bike, you ride in front of the car, grabbing the toddler in one hand. If the combined mass of you and the bicycle is 95 kg, the toddler has a mass of 20 kg, and you are initially traveling at 25 m/s, what is your final velocity after you have grabbed the toddler?
