A jet plane is flying horizontally with a speed of 500 m/s over a hill that slopes upward with a 3% grade (i.e., the "rise" is 3% of the "run"). What is the component of the plane's velocity perpendicular to the ground? (Assume the +x-direction is up along the slope and the +y...

HELP! I'm doing a webassign, and am completley lost on these problems. If you could help with any, that would be great. A crate weighing 9.40 103 N is pulled up a 36° incline by a force parallel to the plane. If the coefficient of kinetic friction between the crate and the ...
