Answer:
Explanation:
The formula for kinetic energy is:
KE = (1/2) * m * v^2
where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
We are given the mass of the pick-up truck as 1500 kg and its velocity as 31.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:
KE = (1/2) * m * v^2
= (1/2) * 1500 kg * (31.0 m/sec)^2
= (1/2) * 1500 kg * 961.0 m^2/sec^2
= 720750 J
Therefore, the kinetic energy of the pick-up truck is 720750 Joules.
