In order to calculate kinetic energy, you need to know both the mass and velocity of the object. Without the mass value, it is not possible to directly calculate the kinetic energy. Mass is an essential parameter in determining the energy associated with an object's motion.
The formula for kinetic energy is:
Kinetic Energy = (1/2) * mass * velocity^2
If the mass is unknown, you would need to have access to the mass value through measurement, estimation, or some other means to calculate the kinetic energy accurately.
Without the mass, it would not be possible to calculate the kinetic energy directly.
