Joaquin has hockey practice at the same ice rink where Alton has curling practice. One day, they were both playing on the ice with their equipment. They noticed two crashes in particular: In Crash 1, Alton's curling stone with more mass was moving along and crashed into Joaquin's hockey puck. In Crash 2, Alton's curling stone with less mass was moving along and crashed into Joaquin's hockey puck. It was the same hockey puck with the same mass in both crashes. Joaquin and Alton want to know about the motion of the hockey puck after the crashes. Why would the crash affect the hockey puck, and which crash would cause a greater change in motion for the hockey puck?

Maxim Chan · Answer 1

the puck recoils in each case.

larger mass stone gives puck greater recoil, smaller stone, smaller recoil

Tomas Palmer · Answer 2

The correct answer is the greater the mass, the greater the force. The hockey puck will move a greater distance in crash 1 than in crash 2.

Explanation:

The force with which a body moves depends on the acceleration it has and its mass. Since the bodies are solid, inelastic shocks are produced, in which all the energy is transmitted from one body to another. In case 1, the impacting body has a greater mass, producing a greater force on the hockey puck, causing it to travel a greater distance. In the second case, being massless, there will be a crash where the body that impacts will be still and the hockey puck will move less than in case 1.

Have a nice day!
