**Unit 5: Work, Energy and
Power**

**Problem Set B**

**Problem 3: **

A volleyball approaches a GBS spiker with a kinetic energy of .441 Joules and a potential energy of 1.209 Joules. If the ball has a kinetic energy of 4.209 Joules as it strikes the ground, then what quantity of work (in Joules) does the spiker do upon the ball? If the value is negative, then enter your answer as a negative number.

Work and energy principles and mathematical relationships can be reviewed on the Set B Overview page.

Further information about the work and energy relationship is available online at The Physics Classroom.
