1. A block of mass m moves without friction on a horizontal plane. The body is connected to a massless string which slides without friction over a fixed pulley. A massless pulley is fastened at the other end of the string. Over the pulley, which can rotate without friction, hangs another string which has two bodies of masses 3m and m fastened to its two ends respectively. Their motions are supposed to be strictly vertical. The acceleration of gravity is...

A block (block 5) of mass m5 = 2.3 kg hangs from the end of a (massless) string which runs over a (massless frictionless) pulley. The other end of the string is connected to another block (block 4) of mass m4 = 6.1 kg on a surface inclined at an angle of θ = 27o above the horizontal. The situation is shown below. a) Assuming there is no friction between block 4 and the inclined plane, find the acceleration (magnitude...

A block of mass M = 2.0 kg accelerates to the right on a surface with a kinetic coefficient of friction of MU_k = 0.30 pulled by a massless string which passes over a massless and frictionless pulley as shown. A block of mass m = 1.0 kg hangs freely from the other end of the string. Call the tension in the string T and the frictional force F_F....

A block of mass m1= 4.00 kg moves on the surface of a horizontal
table. The coefficient of kinetic friction k between the table top
and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1
via a string that passes over a frictionless, massless pulley. The
two blocks start from rest and m2 drops by a distance L =1.75 m to
the floor.

A block of mass .5kg is ona table and attached to a block of mass .25kg by a taut massless string. The .25kg block hangs by means of the string, which goes over a pulley. The .25kg block is released, and it descends from rest at a constant acceleration, travelling 1.00m in 1.25s. What is the coefficient of kinetic friction between the table and the .5kg block?

Problem 31 mi ma Two blocks ma = 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 e 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 uk = 0.15. The incline is at the angle...

5. A particle of mass m slides without friction and starting from rest down a block of mass M in which the surface is shaped into a quadrant of a circle of radius R. The block also slides without friction on a table top. Choose two suitable generalized coordinates a) Using the Lagrange-multiplier formalism, find the equations of motion of the mass and the block and the reaction force of the block on the mass (ie. the constraint force b)...

2. A 40.0 kg wagon is towed up a hill inclined at 17.5° with respect to the horizontal, The tow rope is parallel to the incline and has a tension of 542 N. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. (a) How fast is the wagon going after moving 73 m up the hill? (b) What is the magnitude of the normal force acting on the wagon? 3. A 5.00 kg...

2) A massless string across a massless, frictionless pulley connects block of mass 5.35 kg, to block B, of mass 4.27 kg. Block A lies on a smooth ce and block B hangs straight down from the pulley. Block B falls and block A moves across the horizontal surface. Find a) the acceleration of the blocks and b) the tension in the string.
