Asled of mass m is given a kick on a frozen pond. the kick imparts to it an initial speed of 2.20 m/s. the coefficient of kinetic friction between sled and ice is 0.115. use energy considerations to find the distance the sled moves before it stops. m

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
