Two balls with masses of 2.00 kg and 6.20 kg travel toward each other at speeds of 9.0 m/s and 4.00 m/s, respectively. If the balls have a head-on inelastic collision and the 2.00-kilogram ball recoils with a speed of 8.00 m/s, how much kinetic energy is lost in the collision

Explanation:

Given:

Using the law of conservation of linear momentum:

where: final velocity of the second ball

Now the kinetic energy lost in the collision:

Δ KE = (Sum of initial individual kinetic energy) - (Sum of individual final kinetic energy)

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
