Answer:

The kinetic energy of the bus can be expressed as:

K.E. = (1/2) * m * v^2

where K.E. is the kinetic energy, m is the mass of the bus, and v is the velocity.

Substituting the given values, we have:

493900 = (1/2) * 5040 * v^2

Simplifying and solving for v, we get:

v^2 = (2 * 493900) / 5040

v^2 = 195.6349

v = √195.6349

v ≈ 13.988 m/s (rounded to three significant figures)

Therefore, the velocity of the bus is approximately 13.988 m/s.
