Now that it is officially cold and snowy out, you will soon see people unfortunately slipping on ice. When you fall, how do you want to land?

• With bent arms so the time is decreased and force is increased.

• With straight arms so the time is decreased and force is increased.

• With bent arms so the time is increased and the force is decreased.

• With straight arms tot he time is increased and the force is decreased.
