A spring of force constant 235.0 N/m and unstretched length 0.210 m is stretched by two forces, pulling in opposite directions at opposite ends of the spring, that increase to 24.0 N. Part A How long will the spring now be? Express your answer in meters. How much work was required to stretch it that distance? Express your answer in joules.
Problem 12: (10 points) PS 7-71: A spring with spring constant k is stretched a distance x and hooked onto a block of wood of mass m, which sits on a lab table. Then you release the block. The kinetic friction force between the block and the lab table is F equilibrium length? (VS) length? (Vs) initial stretch of x 65 cm, and a constant friction force Fi 2.4 N. (a) What is the initial elastic potential energy stored in...
"A horizontal spring with force constant k = 810 N/m is attached to a wall on one end.

A block of mass m=2.00 kg is attached to a spring of force constant k=500. N/m that lies on a horizontal frictionless surface. The block is pulled back 5.00cm and released. a) How much work was required to stretch the spring? b) What is the speed of the block when it is 2.50cm from the equilibrium point? c) What is the speed of the block at the equilibrium point?
Consider hanging a block with mass m=1.0 kg from a spring with spring constant k=98 N/m. a) How much is the spring stretched at the equilibrium position (the position where the block hangs without bouncing)? b) If we lift the block up to the position where the spring is unstretched, and then let it go, what's the maximum speed of the block as it bounces? (neglect any friction) c) At the lowest point of the block's bounces, how much further...
