Calculate the translational kinetic energy of Earth as it orbits the Sun once each year (the EarthA????1Sun distance is 1.50 x 1011 m). Compare the translational kinetic energy to the rotational kinetic energy. (Earth is approximately a solid sphere, has a mass of 5.98 x 1024 kg, a radius of 6.38 x 106 m, and completes one rotation about its central axis each day.)
A cab driver picks up a customer and delivers her 1.80 km away, on a straight route. The driver accelerates to the speed limit and, on reaching it, begins to decelerate all at once.
