After pushing a 27.8 kg kid and tricycle over 8.2 m of smooth, level sidewalk from rest, the "combo" is moving at 3.8 m/s. Find the combo's kinetic energy. Submit Answer Tries 0/10 And, what net force must have been delivered to the combo? Submit Answer Tries 0/10 Now you stop pushing and let the combo coast to a stop. The only force stopping the combo is the force of friction. If the force of friction is 6.9 N, how far will the combo coast before it stops? Submit Answer Tries 0/10

You are meeting your friends at a 49er football game. You start near the top of the seating area (8.9 m above the field) and walk down the steps to where your friends are sitting (3.4 m above the field). Assume that your mass is 60 kg. What is the change in your gravitational potential energy as you walk down the steps? Give your answer in J and report your answer to 1 decimal place. Make sure you include the sign if that is important for your answer.
Do #9 from the Energy WS 4 which is posted on Canvas. Make sure you define your system, draw your bar graphs, and write the conservation of energy equation. Finally solve symbolically and plug in for an answer.
