A spring is attached to a wall, and a 0.50 kg block is attached to the other end of the spring. The spring-block system sits on a frictionless surface so that the block is able to oscillate without losing energy. The spring constant of the spring is k = 25 N/m. The block is pushed so that it compresses the spring by 20 cm beyond its equilibrium position. The block is released from rest at exactly the same time as...

A 0.019 kg block on a horizontal frictionless surface is attached to a string whose spring/force/elastic constant k is 120 N/m. The block is pulled from its equilibrium position at x=0 m to a displacement x=+0.080 m and is released from rest. The block then executes simple harmonic motion along x-axis (horizontal). When the displacement is x=0.051 m, what is the kinetic energy of the block in J?

A block of mass m = 4.5 kg is attached to a spring with spring constant k = 610 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 29° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.13. In the initial position, where the spring is compressed by a distance of d = 0.19 m, the mass is at...
