Extracted text: 1. Find the enter of mass and geometric center of the following figures: B cms 3 cms 6 cms b. d. 2m 2m 2. A plane has to drop a food package to refugees. It travels at 200 km/hour. If the mass of the package is 20 kg with what momentum will it hit the ground? 3. An electric canon fires a shell at initial velocity of 20 m/s and an angle of 20 degrees. If the mass of the shell is 8 kg, what is its momentum 3 meters above the ground on its upward motion?
