Your little sister (mass 25.0 kg) is sitting in her little red wagon (mass 8.35 kg) at rest. You begin pulling her forward and continue accelerating her with a constant force for 2.45 s, at the end of which time she's moving at a speed of 1.80 m/s.
Part A: Calculate the impulse you imparted to the wagon and its passenger.J=______
Part B: With what force did you pull on the wagon?F=______
