Amass slider m = 0.200 kg rests on a frictionless horizontal air rail connected to a spring with a force constant k = 5.00 n / m. you pull the slider, stretching the spring 0.100 m, and then release it from rest. the slider returns to its equilibrium position (x = 0). what speed does it have when x = 0.080 m?

Asteady current of 1 ais flowing through a conducter calculate the number of electrons that flows through conductor in 1second

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
