In an attempt to pollute the fine sport of curling, the dastardly Swedish team uses a curling stone with a mass of 24.38 kg instead of a regulation stone with mass of 19.14 kg. If the Swedish rock sails down the ice and collides head-on at a speed of 1.307 m/s with a Canadian team stone (at rest). After an elastic collision, the Canadian stone moves off the target. If it is moving across ice with a coefficient of kinetic friction µk = 0.0498, how far does it move before it comes to rest? Express your answer in metres.
Use Green's theorem to calculate the work done when a particle is moved along the helix x = cos t, y = sin t, z = 2t from (1,0,0) to (1,0,4pi) against the force F(x,y,z) = -yi +xj +zk.
