... A 45.7 kg circus acrobat drops from a
height of 1.79 meters straight down onto a springboard with a force constant of 5.87 x 103 N/m, as
shown in the figure. By what maximum distance does she compress the spring?
A7. Consider a spring-mass system as shown in the diagram, which consists of 1.0 kg block
held by three identical springs with force constant k = 100 Nm', as shown in Fig. A7.
Fig. A7
(a) Consider the block being displaced by a distance x m to the left. Determine the net
force (both magnitude and direction) acting on the block by the springs.
(b) The block is then released from rest. Show that the block performs simple harmonic
motion, and determine the frequency of oscillation.
can i please get help on this type of problem please. I would really apprecite it.
A muscle cell (fiber) in a biceps is 20cm long and contains 1500 myofibrils arranged parallel to each other. Each myofibril is made up of many sarcomeres, organized in series, that behave as springs. A relaxed sarcomere is 2μm long. When contracted, the cell shortens to half its length and develops a force of 30mN. Each of those structures, the cell, myofibril and sarcomere, can be modeled as a spring.
a) Calculate the spring constant of a muscle cell.
b) The 1500 myofibrils in the muscle cell are arranged in parallel. Calculate the spring constant of a single myofibril.
c) The myofibrils are composed of sarcomeres that are arranged in series. Calculate the number of sarcomeres in each myofibril then calculate the spring constant of a single sarcomere.
d) When we shiver in the cold, our muscles oscillate at a frequency of 10Hz and with an amplitude of 2cm. Assume a muscle is a simple harmonic…
