Two curling stones collide. Each has the same mass of 19 kg.
Assume the ice is uniform and ignore the effects of spin (i.e. it
doesn’t “curl”). Initially stone 1 is moving at 5 ms , while stone
2 is at rest. After the collision, stone 1 moves off at 40 ° from
its original path.
a. If the final speed of stone 1 is 3 m / s, then what is the final
velocity (in magnitude and angle) of stone 2.
b. Again if the final speed of stone 1 is 3 m / s, then show that
this collision is not elastic.
b. If the collision is elastic, then what is the final velocity (in
magnitude and angle) of each stone?

In a curling match, two stones (B and C) are side by side in the "house" at the end of the ice, and the opposing player sends her stone (A) to knock them out of play. The mass of each curling stone is 20 kg. The direction of the initial velocity of stone A is east. The two stationary stones B and Care struck simultaneously by stone A causing stone B to move in the direction 25.7 north of east...

A stone used in the sport of curling has a mass of 18.0 kg and is initially at rest, sitting on a Flat ice surface. It is pushed with a constant force of magnitude 24.0N over a distance of 4.00 m. (You may assume that any friction between the stone and the ice is negligible.) (a) (i) What is the acceleration of the stone and what is the work done in accelerating it? (ii) By considering the conservation of energy...

Sliding on the Ice In the winter sport of curling, players give a 20 kg stone a push across a sheet of ice. The Slone moves approximately 40 m before coming to rest. The final position of the stone, in principle, onlyndepends on the initial speed at which it is launched and the force of friction between the ice and the stone, but team members can use brooms to sweep the ice in front of the stone to adjust its...
