What is WgWgW_g, the work done on the block by the force of gravity as the block moves a distance LLL up the incline? Express the work done by gravity in terms of the weight www and any other quantities given in the problem introduction

You have a pick-up truck that weighed 4,000 pounds when it was new. you are modifying it to increase its ground clearance. when you are finished

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?

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?
