Amoving van travels 10km north, then 4 km east, drops off some furniture and then drives 8 km south. (a) sketch the path of the moving van. (2) how far is the van from its starting point? (hint: it is the magnitude of the displacement vector).

4.47 km

Explanation:

If we draw the path of the van then we get a shape with two exposed points A and D. If we draw a line from point D perpendicular to BA we get point E. This gives us a right angled triangle ADE.

From Pythagoras theorem

AD² = AE² + ED²

Hence, the van is 4.47 km from its initial point

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
