Nhat force is necessary to accelerate a 1400 kg car at a rate of 3.0 m/s? ?

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.)

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

What does the law of conservation of mass state?
