Question

A light spring of force constant 4.25 N/m is compressed by 8.00 cm and held between a 0.250 kg block on the

left and a 0.490 kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released

simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if

the coefficient of kinetic friction between each block and the surface is the following. In each case, assume

that the coefficient of static friction is greater than the coefficient of kinetic friction. Let the positive direction

point to the right.

µk 0.250 kg block 0.490 kg block 0.000 : ______m/s ______m/s 0.100 : ______m/s ______m/s 0.465 : ______m/s ______m/s
