In figure, a block A of mass 2kg is moving to the right with a speed 5m//s on a horizontal frictionless surface. Another block B of mass 3kg a massless spring of spring constant 222N//m attached to it, is moving to the left on the same surface and with a speed 2m//s . Let us take the direction to the right as the positive X- direction. At some instant, block A collides with the spring attached to block B. At some other instant , the spring has maximum compression and then, finally, blocks move with their final velocities. Assuming that (i) the spring force is conservative and so there is no conversion of kinetic energy to internal energy and (ii), no sound is made when block A hits the spring, answer the following questions. What will be the the velocity of block A?

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
