Two blocks are connected by a massless string over a pulley. Block 1 has mass mi=20kg and is on horizontal table Block 2 has toas my = 10kg and is on a ramp inclined at angle A = 30" The pulley has a mass M-15 kg and radius R = 20 and can be treated like a disk with uniform a distribution. The string never slips against the pulley. mi a) Supposem travels 4 m to the right when m2...

Problem #1 mi m2 Two blocks mı = 4 kg and m2 = 9 kg are initially arranged as shown in the figure. They are tied to a massless rope going around the pulley. The pulley has a form of a cylinder with a mass of M = 8 kg and radius of R = 40 cm. Both the incline and the horizontal surface have a coefficient of kinetic friction ulk = 0.15. The incline is at the angle 0...
Two blocks of mass m1 and m2 > m1 are drawn above. The block m1 sits on a frictionless inclined plane tipped at an angle θ with the horizontal as shown. Block m2 is connected to mı by a massless unstretchable string that runs over a massless, frictionless pulley to hang over a considerable drop. At time t = 0 the system is released from rest. a) Draw a force/free body diagram for the two masses. b) Find the magnitude of the...
An aluminum block of mass mı = 3.85 kg and a copper block of mass m2 = 7.00 kg are connected by a light string over a frictionless pulley. They sit on a steel surface as shown in the figure below, where e = 39.09. (See this table for the appropriate coefficients of friction). Aluminum Copper Swel (a) When they are released from rest, will they start to move? Yes No (b) If the blocks move, determine the magnitude of...
A block of mass Mı sits on a table, with no friction, and a block of mass M2 is suspended by a cord of negligible mass over a frictionless pulley. At t = 0s the 4) blocks (initially at rest) are released, and the hanging mass starts to descend. Student X says: "The hanging mass is pulling down on the rope, so the tension in the rope is M.g. That's the force on the block on the table, so that...
 A mass m1 = 4.3 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 3.4 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.87 m. 1-How much work is done by gravity on the two block system? 2) How much work is done by the normal force on m1? 3) What is the final speed of the two blocks? 4)...
4. [14pts total] In class we solved a variation on the Atwood machine to find the mag- nitude of the acceleration of the masses, a, and the tension in the string connecting them, T. Now consider this arrangement: e me 02 / Figure 1 If we had solved the case shown in Figure 1, where the surfaces are frictionless and the pulley is massless and frictionless, we would have found: (_ (m2 sin 02 – mj sin 01)g (mi +...
