Any object moving with a specified angular velocity is known to be an object that moves in simple harmonic motion. The displacement (d) of an object moving in simple harmonic motion is described by the function d = R sin(wt) such that d is the radius of the rotating object, w is the angular velocity of the rotating object.

of k = 700 N/m. A block of mass m = 1.10 kg is attached to the spring and rests on a frictionless, horizontal surface as in the figure below. The left end of a horizontal spring is attached to a vertical wall, and the right end is attached to a block of mass m. The spring has force constant k. Three positions are labeled along the spring, and the block is pulled to the rightmost position, stretching the spring. The leftmost position, the equilibrium position, is labeled x = 0. The middle position, halfway between the leftmost and rightmost positions, is labeled x = xi⁄2. The rightmost position is labeled x = xi. (a) The block is pulled to a position xi = 6.80 cm from equilibrium and released. Find the potential energy stored in the spring when the block is 6.80 cm from equilibrium. J(b) Find the speed of the block as it passes through the equilibrium position. m/s(c) What is the speed of the block when it is at a position xi/2 = 3.40 cm? m/s
An amusement park ride spins its rider in a circle with a radius of 2.0 m. Determine the minimum frequency of rotation of the circle that would keep the rider from falling if the friction coefficient between the rider and the wall is 0.68. Express your answer in units of Hz (cycles per second). Use g=10 N/kg. Hint: The required friction force is the weight of the person. The normal force of the wall on the rider causes the friction.
A challenge gaining prominence throughout the planet is the increased need for "green" or sustainable energy. In certain parts of the country, wind farms are a viable alternative to conventional energy sources. An average wind turbine, the device which converts rotational motion to electricity, has a maximum capacity of 2.00 MW . However, the wind turbine realistically never runs at full power. If a wind turbine runs at 31.0% capacity for 1.00 year , how much energy does the wind turbine generate?
To form a pendulum, a 0.092 kg ball is attached to one end of a rod of length 0.62 m and negligible mass, and the other end of the rod is mounted on a pivot. The rod is rotated until it is straight up, and then it is released from rest so that it swings down around the pivot. When the ball reaches its lowest point, what are (a) its speed and (b) the tension in the rod? Next, the rod is rotated until it is horizontal, and then it is again released from rest. (c) At what angle from the vertical does the tension in the rod equal the weight of the ball? (d) If the mass of the ball is increased, does the answer to (c) increase, decrease, or remain the same?
A mass m = 0.55 kg is pushed against a spring with spring constant k and held in place with a catch. The spring compresses a distance x = 0.22 m.

A point-like mass m is constrained to move along the z-axis only. It is attached to two springs, each of spring constant k, and each of rest length 0. One spring has one of its ends fixed at x = 0 and y = h; the other spring is fixed at one end to z = 0 and y=-h as shown in the figure below. Gravity does not act on the system. The springs do not bend but contract and extend along straight lines between their end points. y m (d) Determine the equilibrium position of the system and the frequencies of small oscillations about this equilibrium position.
