Two identical masses are connected to vertical springs each with a force constant k the coordinates x1 and x2 measure the distance of each mass from its equilibrium position write newton's 2nd law for each mass. Assume that x1(t)=A1e^iwt and x2(t)=A2e^iwt. Substitute these into Newton's Second Law and then solve for the eigenvalue problem for the w's. Find the eigenvectors and describe the motion of each mass in those directions
A 100 arrow is shot perpendicularly from a bow whose effective spring constant is 500. If the bow is drawn 75 before shooting the arrow, to what height does arrow rise.

The height of a helicopter above the ground is given by h = 3.35t3, where h is in meters and t is in seconds. How long after its release does the mailbag reach the ground
Four identical particles each have charge q and mass m. They are free from rest at the vertices of a square of side L. How fast is each charge moving when their distance from center of the square doubles.
A person is standing at the edge of the water and looking out at the ocean (see figure). The height of the person's eyes above the water is h = 1.8 m, and the radius of the Earth is R = 6.38 x 106 m. (a) How far is it to the horizon? In other word..
