The mechanical energy is (1/2)k X^2, where X is the amplitude. That equals the maximum kinetic energy, (1/2) m V^2. V is the maximum speed. That means M V^2 = k X^2 V = X sqrt(k/M) k is the spring constant; M is the mass.

ok so here's how i thought i would have to solve these: 1. W=mgh =100*9.8*2.0 or w=0 because u lift the mass upards and carry it (perpenticular ) hence w=0 2. W=f delta D W/D=Force 3. W=60N * 40cm (ordo i convert 40 cm to kg) 4. W=mgh W/h=m (do i convert 4.0 cm to kg?)
