The tension in a ligament in the human knee is approximately proportional to the extension of the ligament, if the extension is not too large. If a particular ligament has an effective spring constant of 160 N/mm as it is stretched, what is the tension in this ligament when it is stretched by 0.760 cm? What is the maximum compression of the spring? The spring sends the block back to the left. How high does the block rise?
A 2.0 kg breadbox on a frictionless incline of angle θ=40° is connected, by a cord that runs over a pulley, to a light spring of spring constant k = 133 N/kg as shown in the figure below. The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless. How far down the incline (in meters) from its point of release does the box slide before momentarily stopping (kinetic energy = zero at this point). Use g = 10 N/kg.
A block of mass 1.6 kg is held against a horizontal spring so that the spring is compressed 17 cm. The block is released and it slides across the floor a distance of 3.4 m before it stops. The coefficient of friction between the block and floor is 0.185. Find the force constant of the spring.
