A 2.0-gram piece of gum is flicked straight at 5.0 meters per second toward a 5.0 gram block at rest on a frictionless horizontal surface. The
collision is shown. The gum sticks to the block and both move to the
right. What is their speed?

The volume of a right circular cylinder can be approximated as follows: volume = ? r2h; where r is the radius of the cylinder and h is the height of the cylinder; ? is a constant that is roughly equal to 3. using the simple approximation above, calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 7 meters
