In the frictionless apparatus shown in Fig. 4.43, m1 = 2.0 kg. What is m2 if both masses are at rest? How about if both masses are moving at constant velocity?
Answer to relevant QuestionsIn the ideal setup shown in Fig. 4.43, m1 = 3.0 kg and m2 = 2.5 kg. (a) What is the acceleration of the masses? (b) What is the tension in the string? A packing crate is placed on a inclined plane. If the coefficient of static friction between the crate and the plane is 0.65, will the crate slide down the plane if released from rest? Justify your answer. A person has a choice while trying to push a crate across a horizontal pad of concrete: push it at a down-ward angle of 30o, or pull it at an upward angle of 30o. (a) Which choice is most likely to require less force on the ...(a) You are told that an object has zero acceleration. Which of the following is true: (1) The object is at rest; (2) the object is moving with constant velocity; (3) either (1) or (2) is possible; or (4) neither 1 nor 2 is ...A 2.50-kg block is placed on a rough surface inclined at 30o. The block is propelled and launched at a speed of down the incline and comes to rest after sliding 1.10 m. (a) Draw the free-body diagram of the block while it ...
