Unformatted text preview: rk done is the sum of that done by gravity (on the hanging block) and that done by friction (on the block on the table). SET UP: Let h be the distance the 6.00 kg block descends. The work done by gravity is (6.00 kg)gh and the work done by friction is . EXECUTE: kinetic energy of both blocks: so This work increases the EVALUATE: Since the two blocks are connected by the rope, they move the same distance h and have the same speed v. 6.102. IDENTIFY: In both cases, a given amount of fuel represents a given amount of work that the engine does in moving the plane forward against the resisting force. Write and speed v and in terms of the time of flight T and v. SET UP: In bot...
