Final answer:

The kinetic energy of the bus is 10,140 Joules.

Step-by-step explanation:

The kinetic energy of an object can be calculated using the formula:

Kinetic Energy = 0.5 * mass * velocity2

For the bus, the mass is 12,000 kg and the speed is 1.3 m/s. Plugging these values into the formula, we get:

Kinetic Energy = 0.5 * 12,000 kg * (1.3 m/s)2 = 10,140 J

Therefore, the kinetic energy of the bus is 10,140 Joules.

Answer:

find it yourself too lazy for math but here's the step

Step-by-step explanation:

it's the object mass multiplied by the velocity.
