A spring-block system sits on a horizontal, frictionless surface. The spring has a spring constant k =2000N/m. The mass of the block is 14.5 kg. The spring is stretched out a distance of 20.0 cm and released. The block undergoes simple harmonic motion with a phase constant φ=?. a) if the velocity of the block is -2.00 m/s at t= 0.150 s, what is the phase constant? b) determine the acceleration of the block at t = 0.150 s. c) what...

A spring is stretched a distance of Ax 40 cm beyond its relaxed length of x by a force, F-25 N. Attached to the end of the spring is an block of mass m-9 kg, which rests on a horizontal frictionless surface. After a moment, the force is removed. 1) What is the potential energy of the block due to the spring when it is held in the stretched position? Uclastic Submit 2) What is the total mechanical energy of...

A spring with spring constant 141 N/m is used to pull a 336 N wooden block horizontally across a tabletop at constant velocity. The coefficient of kinetic friction between the block and the table is 0.33. By how much does this spring stretch from its equilibrium length (in meters)?
A 2kg block and an 8kg block are connected by a relaxed horizontal spring with spring-constant...
A 2kg block and an 8kg block are connected by a relaxed horizontal spring with spring-constant 300N/m. You pull the 8kg block with some constant horizontal force. There is a coefficient of kinetic friction between the blocks and the floor of μk = 0.3. After a time, the spring is stretched a certain constant amount, and the system moves with constant velocity. (a) Draw free-body diagrams for both blocks. (b) What pulling force did you apply? (c) How much is...

A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m.
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
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...

1) A 4.0kg cart on a level ground is pulled with a horizontal spring that's stretched 2.0cm from its equilibrium length. The spring constant of the spring is 100N/m. The cart moves with a constant acceleration. Friction may not be ignored. a) What is the magnitude of the frictional force on the cart. b) Now the spring is stretched twice as far from its equilibrium length. Find the acceleration of the cart. 2)A box that weighs 200N is being dragged...
A 14 kg block on a horizontal surface is attached to a horizontal spring of spring...
A 14 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 5.7 kN/m. The block is pulled to the right so that the spring is stretched 15 cm beyond its relaxed length, and the block is then released from rest. The frictional force between the sliding block and the surface has a magnitude of 44 N. (a) What is the kinetic energy of the block when it has moved 3.0 cm from...
