A rope pulls a 63-kg water skier up a 14.0° incline with a tension of 512 N. The coefficient of
kinetic friction between the skier and the ramp is 0.27.
What are the magnitude and direction of the skier's
acceleration?

What is the order of the moon, earth, and sun in a lunar eclipse and a solar eclipse?

Which object is most likely represented by a dot?

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].
