SUMMARY
The kinetic energy of a 3.00 kg object moving with a velocity vector of <6,-1> m/s is calculated using the formula KE = 0.5 * m * v^2. The user correctly computes v^2 as 37, leading to a kinetic energy of 55.5 J. However, the discrepancy with the book's answer of 60.0 J suggests a potential rounding issue or a difference in significant figures. The method applied is accurate, confirming the calculation process.
