Can kinetic energy be negative? Explain.

An scalar quantity can be negative unless it’s a number/measurement. What about K.E.?

Kinetic energy is always positive. Mass and squared speed are both positive. A moving object can always do positive work in striking another object and causing it to move along the same direction of motion.
