SUMMARY
The kinetic energy of a 410 g particle in a semi-spherical bowl of radius 0.9 m, released from rest and reaching a speed of 2.6 m/s at point B, is calculated using the formula KE = (1/2)mv². The correct calculation yields a kinetic energy of 1.3858 kJ, or 1385.8 J. It is crucial to work with consistent units, as 1 Joule equals 1 N⋅m, ensuring accurate results in physics problems.
