A 13-kg block rests on a level floor. A 300-g glob of putty is thrown at the block so that the putty travels horizontally, hits the block, and sticks to it. The block and putty slide 15 cm along the floor. If the coecient of kinetic friction between the block and the floor is 0.4, what is the initial speed of the putty?

Determine what is the mass of the second block : A 0.51-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstretched length triples.

What is the investor second year tax obligation : The investor's income tax bracket is 30%. The long-term capital gains tax rate is 15 percent. What is the investor's second year's tax obligation?

How far can spring be stretched from its unstrained position : The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move..
