1. a curling stone has a mass of 45 kg. it has an initial speed of 1.1 m/s and travels 45 m to hit the target and come to a stop. determine the coefficient of kinetic friction between the ice and the stone.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
