You are out and about in the country and your father sees a rock that he really wants in the yard. now you must get the very heavy rock into the back of a
truck. the truck bed is 3 feet off the ground. your father pulls out a 5-foot plank and begins to set up a ramp. at the same time, you (who know about
mechanical advantage! ) have found a plank that is 8 feet long, and you show it to your father.
which plank will give you the most mechanical advantage? calculate the ma for each plank.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
