Allison is driving a boat across a river. Her speedometer and compass show that she is going 12 miles per hour directly north, but an observer on the shore measures that she is going 13.4 miles per hour east of north. Why do their measurements not align. Thalia is designing a compound machine for her physics class. She wants to set up a system so that she can press down on a lever with 10 N, over a distance of 0.1 m, and the output of the machine will be a 1 N force exerted over 3 m. Is this possible to develop? Justify your answer.
