Q. A crate of mass 10.3 kg is pulled up a rough incline with an initial speed of 1.51 m/s. The pulling force is 97.0 N parallel to the incline, which makes an angle of 20.3° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.97 m

Q. A plane flies 359 km due south, then turns and flies 610 km at a heading north of east, until it's due east of its starting point. If the plane now turns and heads for home, how far will it have to go?
