Answer
According to the calculation results based on physics calculator, ((2*96000J) / (15m/s)^2). Therefore, the zebra's mass is usually around 533 kg.
Explanation
To resolve this question, we can leverage the concept of kinetic energy, which in physics is represented by the formula KE = 1/2*m*v^2. KE corresponds to kinetic energy, m to mass, and v to velocity/speed. Given that the velocity and kinetic energy are already known (15 m/s and 96000 J, respectively), we could use those details to solve for mass. Rearranging the formula to solve for mass, we deduce m = (2*KE) / v^2.
