A 0.200-kg ball traveling horizontally on a frictionless surface approaches a very massive stone at 20.0 m/s perpendicular to the stone and rebounds with 70.0% of its initial kinetic energy. What is the magnitude of the change in momentum of the stone?

Which situation will have the highest resistance? a. long wire and high temperatureb. short wire and high temperaturec. long wire and cold temperaturedshort wire and low temperature

Why don't you see your reflection in water with waves or repples

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
