Physics

A light spring of force constant 4.45 N/m is compressed by 8.00cm and held between a 0.250 kg block on the left and a 0.450 kgblock on the right. Both blocks are at rest on a horizontalsurface. The blocks are released simultaneously so that the springtends to push them apart. Find the maximum velocity each blockattains if the coefficient of kinetic friction between each blockand the surface is the following. In each case, assume that thecoefficient of static friction is greater than the coefficient ofkinetic friction. Let the positive direction point to theright.

Based on the kinetic friction one can figure out the lowerlimit of the static friction which is larger than the kineticfriction Therefore we can decide if a block is going to have anonzero net force or not If the force by the spring is less thanthe static frictional force then the corresponding block will nothave an acceleration net force being zeroCase 1 k0 so both would experience nozero acceleration Theforces that the spring exerts on both blocks would have the samemagnitude and are in opposite directionsThe two blocks will attain maximum speed when See Answer
