How 50 kg cannon ball is shot horizontally from a cannon at a speed of 80 ms. At this speed what will its kinetic energy be?

The kinetic energy of the cannonball can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass of the cannonball (50 kg) and v is the speed of the cannonball (80 m/s). Plugging in the values, KE = 0.5 * 50 kg * (80 m/s)^2 = 160,000 Joules. Therefore, the kinetic energy of the cannonball at a speed of 80 m/s will be 160,000 Joules.
