... Answer: The graph on the right is the stiff spring. Stiff means big spring constant k. For a given x, the spring with the larger k will have the larger PE = (1/2)kx2. Two masses are identical. One is attached to a stiff spring; the other to a floppy spring. Both are positioned at x=0 and given the s ...

Resultant velocity of a horizontal projectile
... To find the normal force, you need to know that it is always perpendicular to the contact surface pushing on the object. So in this case the normal force is acting straight up on the box. So looking at the box, assuming that the pulley is frictionless, the sum of the forces in the Y is 0 so N + T - ...

Driven harmonic motion
... At x = 0, Fs and acceleration are zero, but the speed of the mass is a maximum. As the mass moves past the equilibrium postion, an increasing Fs acts to slow the mass as it moves to the left, stopping momentarily at x = -A, and then reversing directions. Motion is repeated symetrically between ...
