Use the Pythagorean Theorem to find the missing length in the right triangle. 3 m 4 m The missing length is
Different mass crates are placed on top of springs of uncompressed length L_0 and stiffness k. The crates are released and the springs compress to a length L before bringing the crates back up to their original positions. Rank the time required for the crates to return to their initial positions from largest to smallest. 1 ) k= 10 n/m L= 5 cm L_0= 10 cm 2) k= 5 n/m L= 10 cm L_0= 20 cm 3) k= 20 n/m...

Prove that the number of unordered sequences of length k with elements from a set X of size n is n+k−1 k . Hint: For illustration, first consider the example n = 4, k = 6. Let the 4 elements of the set X be denoted a, b, c, d. Argue that any unordered sequence of size 6 consisting of elements a, b, c, d can be represented uniquely by a symbol similar to “··|·|··|·”, corresponding to the sequence aabccd....

Two equal length springs having a stiffness of : K A = 300 N/m KB = 200 N/m Are nested together in order to form a shock absorber. If a two kilogram block is dropped from an at rest position 0.6 meters above the springs, what is the deformation of the springs when the block momentarily stops at the bottom of its path of travel ?
