Two vehicles (a car and a truck) are involved in a collision and stick together. Just before the crash, the car, with a mass of 1200 kg, is travelling North with a velocity of 82 mph while the truck, with a mass of 1900 kg, is travelling West with a velocity of 47 mph (as shown below) (East = 0°, North = 90° , West = 180°, South = 270°)
A tabletop gamer has designed a game that requires three dice to be thrown onto a tray with a measurement grid. To add an extra degree of randomness, the coordinates of the center of mass of the three dice are used as well. The masses of the three dice are 11.10 g, 13.70 g, and 17.30 g, and their respective coordinates after one particular throw are (0.2810 m,−0.2330 m), (−0.1910 m,0.2890 m), and (−0.4790 m,−0.2210 m). What are the resulting coordinates of the center of mass of the dice, xcm and ycm? xcm = ? m ycm = ? m
Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1750 kg and was approaching at 7.00 m/s due south.
