2. Draw a free body diagram, system diagram, and determine the net force in this scenario: A freighter in the Detroit River that is trying to dock is being assisted by two tugboats.
To fight against a current that exerts a force of 25 000 N [S], the freighter's engine exerts
a force of 32 000 N [N]. To assist the docking process, one tugboat exerts a force of
2 500 N [W] and the other a force of 8 200 N [W]. (4 marks)​

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

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.
