Abaseball is thrown directly upward at time t=0 and is caught again at time t=5s. assume that air resistance is so small that it can be ignored and that the zero point of gravitational potential energy is located at the position at which the ball leaves the thrower's hand.

If the speed of a particle triples ,by what factor does its kinetic energy increase?

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

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.
