  1. Hace 1 día · A 3 kg block rests on a horizontal, frictionless surface as shown in Figure. The block is pressed back against a spring having a constant of k = 625 N/m, com...

  2. 13 de may. de 2024 · A body 𝐴 of mass 180 g is resting on a smooth horizontal table. It is connected by a light inelastic string that passes over a smooth pulley, fixed to the edge of the table, to another body 𝐵 of mass 120 g hanging freely vertically below the pulley. When body 𝐴 is 90 cm away from the pulley, the system is released from rest.

  3. Hace 5 días · Block A of weight 100 kg rests on block B and is tied with a horizontal string to the wall at C. Block B weights 200 kg. The coefficients of friction between A and B are 0.25 and between B and surface is $\dfrac{1}{3}$ The horizontal force $F$ necessary to move the block B should be ($g=10m{s^{ - 2}}$)

  4. 1 de may. de 2024 · A block of mass 1.6kg is placed on a rough plane inclined at 45deg to the horizontal. The coefficient of friction between the block and the plane is 1/4. Model the block as a particle and hence find the acceleration of the block down the plane. Find the velocity of the block after 2 seconds, assuming that it starts from rest.

  5. 24 de abr. de 2024 · Block B, with mass 5.00 kg, rests on block A, with mass 8.00 kg, which in turn is on a horizontal tabletop. There is no friction between block A and tabletop, but the coefficient of static friction between block A and block B is 0.750.
