A relaxed spring of length 0.18 m stands vertically on the floor; its stiffness is 1130 N/m. You release a block of mass 0.6 kg from rest, with the bottom of the block 0.4 m above the floor and straight above the spring. How long is the spring when the block comes momentarily to rest on the compressed spring

Astring that is fixed at both ends has a length of 1.05 m. when the string vibrates at a frequency of 91.0 hz, a standing wave with five loops is formed. (a) what is the wavelength of the waves that travel on the string? (b) what is the speed of the waves? (c) what is the fundamental frequency of the string?
