The angle a vector makes with the x-axis of a coordinate system must be what size in order to make one or more of its components negative? less than 30 degrees between 30 and 60 degrees between 61 and 90 degrees greater than 90 degrees

It should be greater than 90°.

The components of a vector of magnitude 'V' making angle θ with the x-axis are given by,

Horizontal/x component = VCosθ

Vertical/y component = VSinθ

For for any value of θ≥90°, either of or both the component is negative.

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.

dang that balls went far
