Q3-(25 pts) A block of mass m is attached to an ideal spring with rest (equilibrium) length L and spring constant k on the x axis. m other end of the spring is fixed to a wall Initially, the spring is compressed by an amount L/2 and another block of mass 2m is placed in front of the first block (they are not attached). The system is released at t 0 from rest. Ignore friction and the sizes of the...
A block of mass m = 3.5 kg is attached to a spring with spring constant k = 520 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 21° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.16. In the initial position, where the spring is compressed by a distance of d = 0.14 m, the mass is at...
A block of mass M is attached to a wall by a massless spring with spring constant k. The block is allowed to oscillate on a frictionless surface. A second block of mass m is placed on top of the first block. The coefficient of static friction between the two blocks is his. What is the angular frequency of oscillation, and what is the maximum possible amplitude of oscillation such that the second block will not fly off?
a) A block with mass m is attached to a horizontal spring with spring constant k. The block is at rest on a frictionless surface. A bullet with mass Mbul is fired horizontally with speed vbul into the block, in the face opposite the spring, and sticks to the block. mün m Wbul Are you able to determine the bullet's speed by measuring the oscillation frequency of the system of block and bullet? If so, how If not, why not?
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...
A block of mass m = 3.5 kg is attached to a spring with spring constant k = 780 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 28° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. In the initial position, where the spring is compressed by a distance of d = 0.19 m, the mass is at...
6. Consider a horizontal spring with spring constant k. A block with mass m is pushed far to the left against the spring until the spring is compressed a distance r relative to its relaxed length. A second block, which is stationary and also has a mass m, is located to the right of the spring im rrm a) We release the first block from rest. Due to the force from the spring, it slides to the right and eventually...
Part A: 10 points each (Questions 1-4) 1. A block mass of 3 kg attached with a spring of spring constant 2000 N/m as shown in the Figure below. The amplitude or maximum displacement Xmax is 5m.

A small mass moves in simple harmonic motion according to the equation x = 2 Cos(45t), where "x" displacement from equilibrium point in meters and "t"...
A block with mass m =7.2 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.25 m. While at this equilibrium position, the mass is then given an initial push downward at v = 4.6 m/s. The block oscillates on the spring without friction. What is the spring constant of the spring? What is the oscillation frequency? After t = 0.39 s what is the speed of the block? What is...
1) A block of mass m = 0.52 kg is attached to a spring with force constant 119 N/m is free to move on a frictionless, horizontal surface as in the figure below. The block is released from rest after the spring is stretched a distance A = 0.13 m. (Indicate the direction with the sign of your answer. Assume that the positive direction is to the right.) (a) At that instant, find the force on the block. N (b)...
