A 4.75-g bullet is fired with a velocity of 120.0 m/s toward a 20.0-kg stationary solid block resting on a frictionless surface. What is the final velocity if the bullet gets embedded in the block?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
