Q1. An 8kg sled is initially at rest on a horizontal road. The sled is pulled a distance of 3.2 m by a force of 36N applied to the sled at angle of 30o to the horizontal.

Find the change in the kinetic energy of sled.

Q2. A recent tomb has been unearthed in Egypt that shows the set of wall paintings and hieroglyphics of stars falling to and rising above the horizon over the course of the year (these stars served as sentinels for the pharaoh's passage through the underworld). How would astronomers use this data to date tomb?
