2. How far would a spring, with a spring constant of 350 N/m, have to be stretched beyond equilibrium to produce a velocity of 15 m/s when...?

KE = SPE 1/2*m*v_max^2 = 1/2*k*x^2 x = v*sqrt(m/k) x = 15 m/s * sqrt(0.800 kg / 350 N/m) = 0.72 m

3. How far from equilibrium does a spring (spring constant 350 N/m) have to be pulled back in order for a 250 g object to have a velocity of...?

SPE = KE of object at equilibrium position of spring SPE = (0.5)(0.250)(5)² = 3.125 J 1/2kx² = 3.125 x² = 6.25/350 x = 0.1336 m ≈ 13.4 cm ANS
