Jack and Jill climbed up a hill that had a 30o incline. They boarded a sled, with physics in head, and tried to find their acceleration. Assuming that the surface of the hill is frctionless and that the combined mass of Jack, Jill, and the sled is 180kg, determine their acceleration.

..sliding down a grass hill on a piece of cardboard was a fun summer activity! There was a hill near a park in south St. Louis that had an incline of something like 30 degrees. Once I got started on the top of the hill, I could ride for a distance on the order of 50 meters before arrived at the bottom of the hill. At that time, my mass was just a puny...

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...
