A car has a mass of 1000 kg and a momentum of 12 000 kg m / s.
What is its kinetic energy?

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Oxygen undergoes an isentropic expansion from 120 degree c and 280 kpa absolute to 140 kpa absolute. determine the final temperature of the oxygen and the amount of work per kg of o_2 produced in the process if it is adiabatic.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
