The 8 kg block is then released and accelerates to the right, toward the 2 kg block. the surface is rough and the coefficient of friction between each block and the surface is 0.4 . the two blocks collide, stick together, and move to the right. remember that the spring is not attached to the 8 kg block. find the speed of the 8 kg block just before it collides with the 2 kg block. answer in units of m/s.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

1. jay fills a wagon with sand (about 20 kg) and pulls it with a rope 30 m along the beach. he holds the rope 25° above the horizontal. the rope exerts a 20-n tension force on the wagon. how much work does the rope do on the wagon?
