5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N. Construct a free body diagram showing all the forces acting upon...

1. Your little sister wants a ride on her sled. You agreed and moved the sled-sister combination by pulling it across a level ground with a force of F, at constant velocity of 0.5 m/s at an angle of 50 degrees with the horizontal. Assume that the sled-sister combination has a weight of 350 N and the coefficient of kinetic friction is 0.15. A) Draw a neat free-body diagram B) Calculate your force...
