A 191 g block is dropped onto a relaxed vertical spring that has a spring constant of k = 3.5 N/cm. The block becomes attached to the spring and compresses the spring  10.9 cm before momentarily stopping.  What is the speed of the block just before it hits the spring (assume that friction is negligible)? (Your result must be in m/s and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.8 m/s2.)
