1. A 7.00 kg sled is initially at rest on a frictionlesshorizontal road. The sled is pulled a distance of 2.40 m by a forceof 18.0 N applied to the sled at an angle of 24° to the horizontal.Find the change in the kinetic energy of the sled.
2. A 0.24-kg stone is thrown vertically upward with an initialvelocity of 7.10m/s from a height 1.30 m above the ground. What isthe potential energy of the stone at its maximum height relative tothe ground?
