5) Suppose a bolt on your car engine needs to be tightened to a torque of 30 N*m. You are using a 15-cm-long wrench, and you apply a force at the very end in the direction that produces maximum torque. What size force should you apply?

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?
