An elephant, which has a mass of 2200 kg., is moving with a velocity of 11.0 m/s across a frozen lake in Africa when itbegins to slide across the ice. The sliding elephant then collides with a massive 4000.0 kg ball of putty which was left behindwhen a local pottery business went kaput. After the collision the elephant sticks to the putty and both slide across the icetogether. What will be the velocity of the elephant-putty combination?
