The drawing shows a bowling ball suspended from the ceiling of a classroom by a strong cord. The ball is drawn away from its equilibrium position and released from rest at the tip of a student's nose. The student remains stationary. After one swing when the ball returns toward the student, will it hit the student's nose? O No, because air resistance will remove some of the ball's kinetic energy, so ball will reach slightly lower. O Yes, because after one swing it returns even higher than it started. O Impossible to determine without knowing the height of the student's nose.

In order to test energy principles, I decide to do the following experiment with my son at the playground. I push him on a swing so that his initial velocity, at the low point of the arc, is vi=8.0 m/s. His mass is 25kg How high will he swing? Ignoring air resistance, how high will he swing on the other side of the arc?
