4. A 6-kg block (my), initially at rest on a rough shelf, is connected to a 4-kg block (m2) that hangs by an inextensible string of negligible mass passing over a pulley. The uniform disk-shaped pulley, having a mass of 3.0-kg and a radius of 10 cm, rotates about the symmetry axis through its center. The 6-kg block, which is attached to the spring, is initially pushed against the spring compressing it a distance of 30 cm from its equilibrium...

Q3
QUESTION 3 The block with mass of 10 kg is attached with the spring located on the smooth plane as shown in Figure Q3. The plane has been raised to 8 =30° from horizontal surface. When the force F= 200 N is applied, the block started moving down the plane with a speed of 2 m/s. We know that when s = 0.4 m, the spring in an unstretched condition. Given the spring has a stiffness, k=300 N/m (a)...

Can you please solve and explain your work? The correct answer is 7.35 m/s. A block with mass 0.500 kg is attached to a horizontal spring and moves in simple harmonic motion on a horizontal frictionless surface. The spring has a force constant 400N/m. The amplitude of the motion is 0.300 m. What is the speed of the block during its oscillations when it is displaced 0.150 m from its equilibrium position? (this was part 2 of a question, in...

1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
