Two carts, each with a mass of 2.5 kg, move toward one another. a. If the cart moving left is traveling at 10 m/s and the cart moving right is traveling at 8 m/s, what is the magnitude and direction of the total momentum of the system?
b. What is the total momentum of the system if the two carts have the same speed?

28. a stone is projected at a cliff of height h with an initial speed of 42.0 mls directed at angle θ0 = 60.0° above the horizontal. the stone strikes at a, 5.50 s after launching. find (a) the height h of the cliff, (b) the speed of the stone just before impact at a, and (c) the maximum height h reached above the grou

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

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?
