Acar with a mass of 600 kg is traveling at a velocity of 10m/s. how much kinetic energy does it have?

When turned about its axis of rotation, which shape could have created this three-dimensional object?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
