Question

Hockey is a sport in which players use hockey sticks to push a puck across smooth ice. At practice one day, three different-colored hockey pucks were sliding on the ice. The green hockey puck has less mass than the black and purple hockey pucks, which have the same mass. A player hit each hockey puck with a stick, but not from the same direction. Use the information in the diagram to answer.

Which puck(s) experienced the strongest force when hit? How do you know?

A. All three hockey pucks experienced the same force because they changed speed by
the same amount.
B. The black hockey puck; it is more massive and has the fastest ending speed.
C. The purple hockey puck; it takes a stronger force to slow down a more massive object than to speed it up.
D. The black and purple hockey pucks; they have more mass than the green puck, but changed speed by the same amount.

Answer 1

Smooth ice reduces the unbalanced forces that would slow the hockey puck. So the answer is C.
