You briefly push a toy car. it rolls 2 meters in about 10 seconds in comes to rest. you estimate that your push gave the car a speed of about 40 cm/s and the car decelerated at a rate of about 4 cm/s2. How much momentum did you transfer to the toy car if its mass is about 100 grams? How much momentum was lost as it came back to rest after being pushed?
