An object of mass of 2.7 kg is attached to a spring with a force constant of k = 280 N/m. At t = 0, the object is observed to be 2.0 cm from its equilibrium position with a speed of 55 cm/s in the -x direction. The object undergoes simple harmonic motion “back and forth motion” without any loss of energy. (a) Sketch a diagram labeling all forces on the object and calculate the maximum displacement from equilibrium of...

A mass is placed on a frictionless, horizontal table. A spring (k = 100 N/m), which can be stretched or compressed, is placed on the table. A 7.00 kg mass is attached to one end of the spring, the other end is anchored to the wall. The equilibrium position is marked at zero. A student moves the mass out to x = 5.0 cm and releases it from rest at t = 0. The mass oscillates in SHM. Find the...

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 metal cylinder with a mass of 1.20 kg is attached to a spring and is able to oscillate horizontally with negligible friction. The cylinder is pulled to a distance of 0.200 mfrom its equilibrium position, held in place with a force of 17.0 N, and then released from rest. It then oscillates in simple harmonic motion. (The cylinder oscillates along the x-axis, where x = 0 is the equilibrium position.) (a) What is the spring constant (in N/m)? _____...
