Two vectors, r with arrow and s with arrow, lie in the xy plane. their magnitudes are 4.40 and 7.45 units, respectively, and their directions are 310° and 84.5°, respectively, as measured counterclockwise from the positive x axis. what are the values of the following products?

The result is a vector perpendicular to the xy plane: 23.38 k

Explanation:

The cross product of two vectors r and s is defined only in three-dimensional space and is denoted by r × s. The cross product is defined by the formula:

r × s =║r║·║s║· Sin θ· n

where θ is the angle between r and s in the plane containing them, ‖r‖ and ‖s‖ are the magnitudes of vectors r and s, and n is a unit vector perpendicular to the plane containing a and b in the direction given by the right-hand rule.

So, the result is:

r × s = 4.40 * 7.45 * Sin (134.5°) k = 23.38 k

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
