Halliday, Resnick & Walker β Kinetic Energy and Work: Problem 62
A 250 g block is dropped onto a relaxed vertical spring that has a spring constant of \( k = 2.5 \text{ N/cm} \) (Fig. 7.31). The block becomes attached to the spring and compresses the spring 12 cm before momentarily stopping. While the spring is being compressed, what work is done on the block by (a) the gravitational force on it and (b) the spring force? (c) What is the speed of the block just before it hits the spring? (Assume that friction is negligible.) (d) If the speed at impact is doubled, what is the maximum compression of the spring?
π Solution Approach
Given: 250 g, 12 cm
Find: (a) the gravitational force on it and; (b) the spring force?; (c) What is the speed of the block just before it hits the sprin
