A block is attached to a horizontal spring and set in simple harmonic motion, as shown in the figure. At what point in the motion is the speed of the block at its maximum? The position of the block when the spring is relaxed is marked by x = 0, and the extremes of the block\'s...

A 0.63-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstrained length quadruples. What is the mass of the second block? My work is as follows: F=kx ...

In the figure, a 4.3 kg block is accelerated from rest by a compressed spring of spring constant 660 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction μk = 0.260. The frictional ...

In Figure (a), a block of mass m lies on a horizontal frictionless surface and is attached to one end of a horizontal spring (spring constant k) whose other end is fixed. The block is initially at rest at the position where the spring is unstretched (x = 0) when a constant ...
