Homework Help: Physics question

Posted by Christina on Thursday, June 21, 2012 at 10:37am.

1.) If the curling stone was initially sliding at 2.97 m/s and stopped precisely 10.8 meters from its launch point, then the coefficient of friction (the ratio between the magnitude of the frictional force and the magnitude of the normal force) was?

3.) Two curling contestants dispute possession of a stone of mass 15.0 kg. The mass of contestant A is 56.2 kg, whereas that of contestant B is 105.2 kg. Contestant A pulls on the stone with a horizontal force of 19.5 N, but is unable to break contestant Bs grip. The result is a stalemate (the stone does not accelerate).

a) Neglecting (for now) frictional forces between the stone and the ice, what is the horizontal force that contestant B exerts on the stone? [Note: Indicate a pull (a force in contestant Bs direction) by a positive sign and a push (a force in contestant As direction) by a negative sign.]
=?N

b) What is the minimum coefficient of static friction required between the contestants and the ice (assume that it is the same for both contestants)?
