Mass #2 (150.0[kg]) is connected to Mass #1 (50.0[kg]) by a single cable that is passed over an ideal pulley. The coefficient of kinetic friction between Mass #2 and the ledge is 0.254. He successfully moves the objects after they were at rest. What is the magnitude of the gravitational force on Mass #1? Express your answer in units of Newtons. What is the magnitude of the gravitational force on Mass #2? Express your answer in units of Newtons. What is the magnitude of the tension in the rope connecting the objects? Express your answer in units of Newtons. What is the magnitude of the acceleration of the objects? Express your answer in units of m/s2.Considering that now I have learned to solve for V & T. My next question is how would I solve for the magnitude & direction of the maximum static frictional force acting on the suitcase? I just began my Physics I course, in your opinion would you consider this word problem to be an intro to physics?
- If there are no external forces acting on a system, the system is considered to be an _____ systemA force, Fapplied, is used to pull a block of mass m up an incline plane for which friction is present. The force is gradually decreased with time, as shown in the graph above. At some point the block starts to slide down the incline plane under the influence of its self weight. Which of the graphs below best shows the magnitude and direction of the friction force, FFriction, exerted on the block?F m₁ 8 A 5 kg block is on a 39 degree incline for which uk = 0.1. It is acted on by a horizontal force of 24 N, as shown in the above figure. a) What is the acceelreation of the block if it is moving up the incline? (enter a positive value if the acceleration is directed up the incline, enter a negative value if the acceleration is directed down the incline) m/s² b) If its initial speed is 5 m/s up the incline, how far does it travel in 2 s? m
