A constant force of magnitude F makes an angle ? (measured counterclockwise) with the positive x direction as it acts on an object of mass m moving in the xy plane. How much work is done on the object by the force as the object moves from the origin to the point having position vector ? State your solution in terms of the given variables.
A bomber is flying horizontally over level terrain at a speed of 260 m/s relative to the ground and at an altitude of 2.60 km. At what angle from the vertical was the bombsight set
