Question

A 260 g block is dropped onto arelaxed vertical spring that has a spring constant of k =2.5 N/cm. The block becomes attachedto the spring and compresses the spring 11 cm before momentarily stopping. c) What is the speed of the block just beforeit hits the spring? (Assume that friction is negligible.)
                            m/s

(d) If the speed at impact is doubled, what is the maximumcompression of the spring? c) What is the speed of the block just beforeit hits the spring? (Assume that friction is negligible.)
                            m/s

(d) If the speed at impact is doubled, what is the maximumcompression of the spring?

Explanation / Answer

are commas suppose to be decimals.
