What is the potential energy of a rollercoaster if it weighs 1000 kg and sits on a 110 m tall ride?

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Which of the following are guidelines to follow for obtaining accurate observations

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value
