A hockey puck slides 55.0 m along the length of the rink in just 1.25 s. The slight friction between the puck and the ice provides a uniform acceleration. If the puck's final speed is 43.2 m/s, what is its initial speed? 31.4 m/s?

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

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].

Aforce of 100 newtons is used to move an object a distance of 15 meters with a power of 50 watts. find the work dine and the time it takes to do the work
