Two blocks are attached to one another, as shown, by means of a massless cord that passes over a massless frictionless pulley. Block 1 (mass 10 .0 kg ) is connected to a spring with spring constant 100 N/m, and block 2 (mass 20 .0 kg ) sits on a frictionless ramp that makes an angle 30 .0

Two masses are connected via a spring and a string over a massless pulley as shown below. The first mass has a mass, m1 = 4 kg, and the second, m2 = 3 kg. The inclined plane sits at an angle, θ = 30°, with a coefficient of static friction with the first mass, μs = 0.3. The spring has a spring constant, k = 4 N/m. How far past its natural length is the spring extended to keep the...

10. A pulley and mass system is setup as shown below. The pulley is not massless, but you may assume there is no slipping of the string along the pulley and that the string is massless. The system starts from rest and the hanging mass is seen to move upwards. There is a tension T1 in the left portion of the string, and a tension T2 in the right portion of the string. Is the magnitude of T larger or...

In the pulley system shown in Figure P2.33, assume that the cable is massless and inextensible, and assume that the pulley masses are negligible. The force f is a known function of time. Derive the system's equation of motion in terms of the displacement. For the system shown in Figure P2.34, the solid cylinder of inertia I and mass m rolls without slipping. Neglect the pulley mass and obtain the equation of motion in terms of x.

Two objects are attached with a massless string over a massless, frictionless pulley as shown below. The horizontal surface is frictionless. Draw the free body diagrams for the masses. Include the assumed directions for the accelerations of the masses. Write down the expressions from Newton's 2nd Law for the two masses. Clearly indicate the coordinate systems used for each mass. Determine the acceleration of the masses.

As shown, a frictionless pulley hangs from a system of
springs and a cable. The pulley is equidistant between the two
supports attaching the springs to the ceiling. The distance between
the supports is d=1.50 m . The cable cannot stretch and its length
between the two springs is 1.8 m.

Near the surface of the Earth, a student is using a simple pulley to lift a crate of mass M = 30 kg from rest to a height H by pulling on the rope with a constant force F as shown in the figure. If the breaking strength of the rope is 400 N, what is the minimum time (in s) required for the student to haul the crate to a height H = 20 m? (Assume that the pulley...
