8. A weight of 0.5kg stretches a spring by 0.49m. The spring-mass system is submerged in delicious melted butter with a damping coefficient of y=4. The spring is then lowered by an additional 1.0m and released with velocity 0. There is no external force. Find the function which gives the location of the weight at time t. Note: I have designed this to work out nicely. If it's not working out nicely then you probably got some butter in your calculations.
At an outdoor market, a bunch of bananas is set into oscillatory motion with an amplitude of 20.0 cm on a spring with a force constant of 16.0 N/m. It is observed that the maximum speed of the bunch of bananas is 43.0 cm/s. What is the weight of the bananas in newtons? N
The system composed of two springs and a particle with mass ? shown in the figure can beconsidered as a system with a single equivalent spring. Suppose you move the particle and stretchboth springs (since the force constants are not the same, it cannot be assumed that both springs arestretch the same, you must find a relationship between how much each spring stretches and the displacement of the spring.particle). Determine an expression for the equivalent spring constant in terms of the constantsof each spring.
