I REALLY NEED HELP WITH THIS: The ball has a mass of 2 kg and a final speed of 5 m/s. What is the kinetic energy of the ball? Give your answer in joules (J). Recall that the equation for finding kinetic energy is "Kinetic Energy = 1/2 x mass x speed²"

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
