You walk 4 kilometers north then 3 kilometers east. This takes you 2 hours. What was your average velocity?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

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].

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
