Aforce of 30 n is extremed on an object on a frictionless surface for a distance of 6.0 meters. if the object has a mass of 10 kg, calculate its velocity

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
